hey guys! thank you all so much for your constant love and support over here on KZfaq! If you click the notification bell for "all" notifications, you will find $100 on the ground in the next month. Probably not, but if I see you in public, I'll give you a cookie. Ehh probably not that either. Just hit the notification bell! :)

Him - "Stupid question..." Me - "There are no stupid questions." Him - "Could he take his helmet off and breathe on Mars?"

"For a botanist he sure knows a lot about the machinery." That's actually explained in the book, and I'm genuinely not sure why they didn't include it in the movie. In the book, while he's a botany expert, he's also kind of the crew's "handyman" who knows how to do a little bit of everything. Which is why, in this movie... well, he knows how to do a little bit of everything.

My favorite bit of trivia for this movie: In the script, it said that Mark started crying the first time he heard the crew's voices. Matt Damon and Ridley Scott took it out because they thought it wasn't authentic. When they filmed it, Matt had been filming alone in the desert for weeks/months, and the first time he heard the rest of the cast talking made him realize what Mark had gone through... and he started crying for real. The reason that moment hits so hard is because Matt's not acting, he's actually crying.

What I like the most about this movie, is that there's no actual villain outside of nature and Mars itself. NASA director can be perceived somewhat cold about Mark's fate, but ultimately everybody is working towards the goal of saving Mark

Fun fact in the book when mark is reunited with the rest of the crew he says if this were a movie we would all be hugging in the cargo bay which is exactly what the movie shows

Any time an actor can pull off acting alone and can do a good job at it. Has my respect. No one to interact with makes it a lot more difficult. Like Tom Hanks in Castaway.

The scene where he gets Pathfinder operational is so moving and inspiring it brings me to tears every time and I cant explain it. It's not sad or even really happy crying.. it's just kind of a sense of being overwhelmed at the incredible stuff we as a species can accomplish.

"Mars is a planet with a very similar daily cycle to the Earth. Its sidereal day is 24 hours, 37 minutes and 22 seconds, and its solar day 24 hours, 39 minutes and 35 seconds. A Martian day (referred to as “sol”) is therefore approximately 40 minutes longer than a day on Earth."

I have the feeling Alex never saw Apollo 13. Honestly, after this, I think the forefather of the space accident movies would be great.

I love how the only bad science in this movie is the storm at the beginning

As a software developer, one of the greatest moments of the novel was the hexadecimal communications thing and the rover hacking thing. Extremely realistic! I was so happy it got realistically represented in the movie too.

"Could he take his helmet off and breath on Mars?" Where did you say you got your law degree Alex? and shoutout to the Editor he did a great job and thank you for not editing out his dumbass questions!

I read the book first, never have I laughed so hard at jokes that Mark made. Movie did it a great service too.

If you are at all a book person, I recommend you read the book (and if you're not a book person, I recommend the audiobook while you do chores or exercise or something). The humor is just as good, the science you mentioned you don't know is explained in further detail, and several plot points are deepened/fleshed out/explained (such as Mark knowing so much about the machinery, and the thought processes of the different NASA people working on how to save him, what hexadecimals are, etc.). Thank you for the awesome review!

To the editor: "One does not simply get the reference" Mate, you are crushing it! I really like what you do. It's not intrusive but adds a lot to the whole experience. It's just another layer of fun to the already pretty funny commentary. Very good and subtle way supplement the content. Good stuff!

That editors note about the LOTR thing made my laugh out loud! Thanks for that. Sure wish Alex would get around to watching them soon. The prolonged shot of Alex not getting the reference at all is hilarious!

One thing that didn't make the movie but was in the book, Mark had to convert his water into hydrogen to make more fuel. They also had him convert his piss. He said he couldn't wait to tell his grandkids. "Back in my day, I pissed rocket fuel!"

Not only is this one of my favorite Matt Damon movies, but it's a comfort movie that I watch a lot. It definitely a drama mixed with comedic moments. I loved that you watched the extended edition of this movie. And the cast in this movie is fantastic. This is based off the book of the same name by author Andy Weir. The book is more technical. And it dives more into the friendships with the crew. 16:32 Yep. That's actor Benedict Wong, who plays Wong in the MCU. No matter how many times I watch this movie, the end when the crew goes to rescue Mark always gives me slight anxiety. Looking forward to your next reaction. 😊

Note to editor: The "There I helped" with making his brain bigger was just pure comedic gold. Loved the little detail that most people probably won't even notice. But that is exactly what makes it Sooooo good!

Great reaction! The incident he's talking about is how a group of students at Caltech blew up a part of their dorm building whilst trying to make a rocket. Those same students, after being kicked out, founded their own lab, where invited back later, and eventually formed the Jet Propulsion Lab.

"thanks to my uncle Tommy in China, we got another chance" 😂 So funny

So surprised Alex didn't realize one of the crewmates was Bucky! Especially after recognizing Luis & having the Iron Man reference! 😂 But overall *fantastic* reaction for a fantastic movie, and YES, the humor is on point throughout!

Alex: You’re alone on Mars….WHAT DO YOU DO…..? Mark Watney: You get to work

Quite honestly, one of my favourite films ever. Seeing this the first time was utter joy from beginning to end. Seen it numerous times since and just as great every time.

I'm no mathematician, but I can help with the idea of "hexadecimal," having worked around the concept for a few years. Binary is 'base 2', because it has 2 digits: 0 and 1. Decimal is 'base 10', because it has 10 digits, 0-9. Hexadecimal, often shortened to just 'hex', is 'base 16', because it has 16 digits: 0-9, then A-F, which stand for 10-15. In decimal, for example, we express twenty-six 'things' as 26 (2 in the 10's column, 6 in the one's column; 20+6=26). In binary, that would be 00011010 (1 in the 16's, 8's and 2's columns; 16+8+2=26). In hex, that would be 1A (1 in the 16's column; A, or 10, in the one's column; 16+10=26). So, 26 = 0001 1010 = 1A. One thing that hex allows, is for the same value to be expressed in fewer digits, which can especially be useful with larger numbers. Hex is used in computer-type applications for that reason, and also because 16 is a 'power' of 2. Binary is '2^1', '2 to the first power', or 2 not multiplied again by itself. Hexadecimal is '2^4', 2 to the fourth power', 2*2*2*2=16. This makes it possible to write long binary numbers using fewer hex digits, by expressing each grouping of 4 binary digits as 1 hex digit. So '0000 0100 0000 0000' in binary, 1,024 in decimal, is written as '0400' in hex, or depending on the context, just '400'. Since it's easy to mistake '400' as a decimal number, hex numbers are often designated in one of two ways, either as '400h', or more often as '0x400'. So, when Mark is decoding the hex message at 17:20, the 'H' is 0x48, which is 72 in decimal; 4 in the 16's column, 8 in the one's column, 4*16=64, 64+8=72. How does 72 get you to 'H'? Because of an internationally-recognized alpha-numeric code called ASCII, where 72 means 'H', 79 means 'O', 87 means 'W', etc. Hope that helps understand a bit of the 'science' going on here. Sometimes 'touching bottom' with a concept, or even a part of one, can help ground the rest of the experience, not like floating around in a sea of confusion, making the experience a bit more enjoyable. Cheers!

This is a stunning movie, and the humor is so good it makes it feel like comedy, underrated film!

Editor - AND not knowing that was Sean Bean for sure. Man, the references in this movie were stellar. I wish Alex had gotten them.

"Is he using shit as fertilizer?" Alex, that's exactly what fertilizer is.

"One does not simply get the reference" 😂😂😂😂 My guy you are on point today!! Thanks for being awesome and doing a brilliant job

FYI: If the supposed adaptation of this author's 3rd book - Project Hail Mary - is done proper justice, it will blow this movie out of the water. (That said, I've come to the conclusion that PHM should be a 10-part miniseries to be done right.)

"One does not simply get the reference", man that cracked me up!

8:20 - Sol - The term "sol" is used by planetary scientists to refer to the duration of a solar day on Mars. The term was adopted during NASA's Viking project (1976) in order to avoid confusion with an Earth "day". A Martian day is approximately 40 minutes longer than a day on Earth. It looks like not much.. but add that every day.. and you get another 13 more Earth days (which our mind and digestive system is kind of used to for calory intake) by sol 461, in 31:57 8:47 "shit as fertilizer" - yeah it works that way. Our (or basically any animal) digestive system is not 100 percent efficient, more like 20-30. Most of the nutrients go away. Using it as fertilizer is a proper way to grow food, instead of flushing to ocean.. but hey, there are too many people on Earth from the middle of 19th century to be a self-sufficient cycle (what is added is the energy from the Sun via photosynthesis), so we need to add Nitride in artificial form. Sadly, this destroys the soil, so we are still kind of racing to the bottom...unless new technology will be find. depending on local conditions, 2-3cm (one inch) is generated in 100-1000 years, but with overuse of artificial fertilizers, industrial pollution etc. it is destroyed quickly. 9:11 - "lighting hydrogen on fire" - my guess this mostly relates to the Hindenburg disaster. 23:20 - Jordan. Next to Israel. It is the closest what we have on Earth looking similar how Mars looks. 23:35 - bigger brain would not help. Elephant is not more intelligent. I do not mean it as offence, but learning usually helps. :) Reading books has statistically better result than just passively watching youtube :) I know.. I am writing that on youtube. 29:43 - more of an issue is another year and a half in increased radiation exposure in space. But i guess they solved it to a manageable level, with our current tech Mars is too long space flight for humans - or a too heavy ship with shielding for our engines. 33:00 - during the year and half waiting, I bet he did, multiple times. And then added the extracted minerals to the potatoes, since you have to recycle as much as possible :) 33:19 - I would love to. Even that it is really much easier to create a base on Antarctica (it is cold, but not that cold as on mars, by a hundred of degrees more, there is breathable air, water everywhere in ice and the difference in gravity - just 38% Earth - means moves will be ackward, getting a toll on the body that was designed for different gravity- blood pumping, bones, muscles. More importantly, we do not know yet or sure if it is even possible to reproduce, it seems not in zero-G) But what a sight it would be. I am there at least by spirt, just by having a name on the 2020 Perseverance mission. Next flight is scheduled for Europa, Jupiter, baby.

Weird, I didn’t know there was a directors cut to this movie because I’ve seen this movie dozens of times and there are clips I’ve never seen. I’ll be searching this out tonight. Thank you Sir.

This is literally just one of the best space movies ever.

I always love the fact that an actor in this council of Elrond was also part of the original council.

This, Interstellar, and Apollo 13 are my favorite space films (outside of Star Trek and Star Wars that lack the “grounded” factor these three have So glad you enjoyed this one. VERY sad that the Council of Elrond went right over your head 😂😂 especially with Sean Bean present (I was fangirling so hard during that scene during my first watch)

I'm so glad you watched the Director's Cut! Glad you enjoyed it! Another great space exploration epic is The Right Stuff! It's about the formation of NASA and the first American astronauts to compete with the Soviet space program during the Race to Space!

Hollywood needs filmmakers like Ridley Scott more than ever

here i was thinking it’s okay Alex doesn’t know science, cause he’s a lawyer. but then he couldn’t figure out what “sol” meant. you’d think lawyers would be pretty good with latin root words. it’s a good thing he’s funny 😂

Antmans friend pilots a ship. Invisible girl is a tech genius. The alien from dark phoenix likes disco music. Dr. Stranges 2 best friends Wong and Mordo try to rescue Matt Damon. The winter soldier flies an eva suit. A criminal caught by spiderman sends them back to Mars. Lotta marvel people in this movie.

This is my favourite movie of all time. I've seen it 3 times in cinema and i can't count the rewatches i did at home. And, i think, this is one of the few movies that lives up to the book that it is based on. Sure, some things are different or left out, but it is one of the best adaptations out there by far. Andy Weir is an amazing author and i hope his other books will get movie adaptations as good as The Martian.

One of my favorite space movies of all time! Matt Damon was an exceptional choice for this film! 👏 Excellent job Captain Blonde Beard♥️

This is my favourite movie of all time. Great script. Fantastic cast. Good humour. Awesome story. It’s just about people achieving together. Makes me cry, every time.

One of my favourite books, hands down. It has it all - drama, terror, comedy. Mark's perseverance and ability to laugh in the face of impending doom is really motivating and so, so hopeful Havent seen the movie since it first came out in theaters. The diary-esque format of the book made a lot of the moments more dramatic, but the movie is still pretty good, and the actors are phenomenal of course. One thing im still mad about is that in the book Teddy (i think it was him) always had two speeches prepared in case of successful/unsuccessful launch, but when asked about it after Mark got rescued he confessed he'd only written one speech this time, the one for success. They cut that from the movie, and I'm still shitter-shattered about that 'cause I love this detail

I think his name was Donald Glover. He said he truly slipped in that one scene. But he and they kept it going. There was some drink spilled and there you go

I love that the most unscientific part of this movie is the storm at the beginning. Not enough atmosphere to have winds that strong.

If you're getting into a space movie phase, I really recommend watching "Moon" (2009), with Sam Rockwell and directed by Duncan Jones (David Bowie's son). For a first movie, i think Jones did a great job with it :) It is quite slow-paced, and as I remember it pays a good homage to 2001 A Space Odyssey, so it's worth the watch

yo alex i just wanna say thank you for being you man i have been watching you for the past 4 years and your videos have helped me through the death of my late mother, being taken away from my fam. you have helped me thru so much so thanks man. Its always a gooch slappin time when you post something new love you bro peace

A full range of emotions is what this movie is

I've read this book 3 times and watched this film at least 6 times... THEY NAILED IT.

This is one of my fly paper movies. Those are the ones that if I come across it while channel hopping, I'm stuck there until the end of the movie. It's just so much fun and very re-watchable.

I have not laughed as hard as I did when you asked if he could breathe on Mars for a long time. LMFAO thank you for that

One of my FAVORITE Matt Damon movies, it's a perfect blend of humor and intensity. Earlier in the video you mentioned the cast, but twice you didn't see one in particular. Sebastian Stan, who plays Bucky Barnes (The Winter Soldier) also plays in this. He's one of the crew members that goes back to rescue Mark.

I read the book before the movie came out but knew Matt Damon was playing Watney. It's remarkable, almost like Andy Weir had Damon in mind when writing it - he IS Mark Watney! Ridley Scott hit this one out of the park with casting, script, cinematography & direction.

Alex's channel is the only one where I don't skip straight to the reaction and move on when it's done. Fantastic entertainer. So talented. Perfect comedic timing. I always watch the Intro and Outro.

In the book (or maybe just the audiobook) instead of the college scene at the end commander Lewis takes him for a burger and he aggresively declines to accept french fries with his burger despite them being included in the meal, and then she tries to recruit him for a private spacetourism company that is looking to hire retired astronauts.

A Sol is a Martian day, which is 39m 35s longer than Earth's.

The one big problem that you just have to look past is that in order to have a storm like at the beginning, the atmosphere needs to be much denser. There isn't just different gas contents, but lower air pressure in general. I don't know how they explain him being left behind in the book, but I feel it's a lot more boring or complicated, so they changed it for the movie. A Sol is a planetary rotation, and a Martian Sol is 24 hours and 37 minutes, according to Google.

Love your reaction. 🙂 I'm a month late, so someone's probably already mentioned it, but (true story), the astronauts almost all have dual specializations. This is explained in the book, but basically, Mark has pretty much the BEST skill set for his situation. He's a botanist and a mechanical engineer.

Using human waste as fertilizer isn’t particularly good for you; but it’s less bad than not eating at all. Same as the “don’t drink unboiled water in the wilderness, unless you’re literally going to die of thirst” thing. If you’re physically incapable of boiling it, and you haven’t drank anything in two days; then getting parasites is less bad than not living long enough to get them treated in the hospital, because you died of thirst in the wilderness.

I laughed when you mentioned your wife looks dead on the gross stuff and how you hide, as me and my wife are the exact same way. Growing up I couldn't take the fake blood operation stuff on MASH and to this day I'm the same way. Surprisingly when my son was born I thought I would have issues, but I was fine, and my step daughter actually passed out.

Mark Watney as Iron Man The Winter Soldier The Invisible Woman Ant-Man's buddy Luis Spider-Man Miles Morales' uncle Aaron - The Prowler Baron Mordo Wong This movie is Marvel AF....

“And that’s assuming nothing goes wrong” Murphy’s Law: “you called?”

Can I just say for the last few weeks I’ve been binging your review videos and they are so good. You seem like such a genuine nice guy , so funny as well. I was feeling a bit down but your videos have helped me see positivity thanks for that and keep up the GREAT work. Peace bro

Amazing movie...much of which is based on true facts and science. You did a GREAT job of reacting.....

“Gravity” with Sandra Bullock and George Clooney is an amazing movie. You hardly hear about it but it’s really good. If you haven’t seen it, I’d love to see a reaction. It’s amazing, wholesome, part horror movie, and will crank your anxiety all the way up (in a good way).

Bro recognises Louis from Antman by name but didn't even see the god damn Winter Soldier floating around in that same ship. 😂😂

Yeah, it’s a dramedy. Definitely some funny bits.

Every time I now watch Interstellar I think they’re going to find Matt Damon’s character growing potatoes ❤

"He's got sprouts! Holy Sh!i!" I see what you did there. A "sol" is one solar day on Mars, from noon to noon. (Sol is the actual name of the star we call our sun - because scientists are obsessed with using a dead language like Latin to name everything). It's about 40 minutes longer than a 24-hour solar day on earth.

From what i remember, Mars does have oxygen in its atmosphere, but there's so little of it that you still need a helmet to breathe

I do believe they filmed in Wadi Rum. A particular fav for the director, Ridley Scott. He filmed there for Prometheus and Alien Covenant as well, if I recall. Also, I VERY MUCH recommend the audiobook of the Martian! It's narrated by Wil Wheaton. The book has a lot more detail and backstory that obviously can't always make the film cut. Overall, Andy Weir crafted a really amazing story & character, for sure. I loved this book and film.

If you're in the mood for one-off movies that are great, I suggest 2016's Arrival. I saw it for the first time a month ago and loved it. I'd go into it knowing as little as possible if you can :)

I loved this movie when I first saw it and I agree with what you said about the soundtrack. While a lot of the movie is filled with jokes there are those serious moments that bring back in the tension and then when the soundtrack hits brings us back into that fun adventure again. I think it's great that you're looking into standalone movies rather than cinematic universes too. Sometimes you just want to sit and watch one story for what it is. If you're looking for a hidden gem in these types of movies I recomend The Life of Pi. Without going into spoilers, it's a beautiful story of a boy trapped at sea with amazing imagery and storytelling.

fun fact, storms on mars are phsyically not able to get that bad. some of the strongest winds on mars only get to about 60 miles per hour. thats due to the extremely thin atmosphere on the planet. overall though the movie and the book series are extremely scientifically accurate, to a point. obviously a few things have to be highly exaggerated for the sake of plot, and well its a movie. but many things were so well done when it came to scientific accuracy. in the book he did not ironman his way back to the hermes, but mark DID suggest doing that. Commander lewis immediately vetoed the idea and watney listened because well, chain of command. they problem solved their way out of it.

This might be the best book to movie adaptation I've ever seen. All the characters were perfectly cast and portrayed, most of the scenes and dialogue were practically beat for beat from the book, and Matt Damon captured Watney's humor spot on! There's one line from the book I wish they had used. Watney is talking about growing potatoes in his poop and says "My a**hole is doing just as much as my brain to keep me alive." 😆

the humors in this movie is absolutely necessary, because in that kind of situation people can go crazy easily

You'd panic? You're not qualified to be an astronaut. The people who go on these missions are expected to remain calm in extreme circumstances so only the best gets selected for missions to space. 9:40 Planning to go to Mars for vacation or something? Best start preparing. He knows about machinery because as an astronaut he's expected to have enough skills to be able to make repairs or other such stuff. From the quick research I did about the failure rate of launches, they range from 5 to 30%. I enjoyed your reaction, this is a good movie.

My wife used to manage a catering company in Hollywood. Met Matt several times. She catered a party at his home. The usual suspects were there. Ben Affleck , Don Cheadle, Jennifer Garner, George Clooney, etc. Before the party, as guests were shuffling in she was in his kitchen prepping. He comes down from upstairs and begins making PB & J sandwiches for his kids who were hiding out in the game room. Mind you , there was caviar and other exquisite foods. Nope. Kids wanted PB & J . And being a good dad he obliged. He even offered to make her one. She said he was truly one of the most humble and kind actors she ever met. And she's met most of the big names.

i have watched this movie at least 20 times now, but every time its same emotions and chills.

To me, The Martian is a story about Humanities capability to move heaven and earth when we come together. An excellent example of this in real life is the Berlin Airlift that happened after WW2. It's a pretty long story, I recommend checking out Fat Electrician for the full story, but basically, it's a story of impossible timing, coordination, and logistics to feed half of Berlin via cargo planes. On a smaller note, Mark is an excellent example of how powerful hope can be. You can curl up and die quietly, or you can rage against the dying of the light and forge your own path. Once you see a sliver of hope, you will blitz your way to that path. I love this film, and I really need to read the book.

The thing that initially hit Mark WAS the communication antenna; that is why, until Pathfinder was utilized, there was no communication possible between Mars and anyone else.

I've already told my kids if I EVER got a chance to go live on Mars I'd go in a second

The Chinese weren't better than us Captain Goochbeard. They had that rocket prepped and checked out and no one knew it. It was a state secret with them, so them helping was admitting they had that rocket.

Fun Fact! There's a TON of MCU alumni in this movie: - Michael Peña (Luis in Ant Man) - Benedict Wong (Wong in Doctor Strange) - Chiwetel Ejiofor (Mordo in Doctor Strange) - Donald Glover (Aaron Davis in Spiderman: Homecoming) - Kate Mara had a little role in Iron Man 2 - Matt Damon played Loki in the play in Thor: Ragnarok - and my personal favorite: Sebastian Stan (Bucky Barnes aka the White Wolf aka the Winter Soldier!!)

Whoever the editors, I love them the editor note are hilarious, especially since I’m Lord of the rings fan and all the other videos it’s hilarious good choice on hiring and editor Alex

@Alex fun fact, in the original book, the crew had a plan in case they messed up the supply rendezvous and didn't have the supplies needed to make it to Mars and back. Beth Johansen would be forced to become a cannibal and eat the other crew members after they immediately take pills to not waste their remaining food. Its pretty horrific. Also, Mark is able to repair/build things with relative ease because he is also the backup engineer/SysOp technician and would have a background in repair (alongside having the manuals for anything that breaks) giving him better odds to survive than the rest of the team (because of his botany background)

That actor is Sean Bean, who also played Boromir, one of the two men who attended the secret meeting at Elrond, in the film, LOTR. And yes, he also played Ned Stark.

"For a damn Botanist, he sure knows a lot about the machinery" YEAH, ASTRONAUTS CAN DO EVERYTHING because they have to!

I think the main reason he started crying was more so that, that was the first voice he heard for so long.. and it was the voice of a friend to boot.

Fun fact: about 12 or 13 years ago, there was a call for anyone who wanted to go to colonize Mars. Only trick, it was a one way trip. I almost signed up for it, but I don't have any skills that would have helped them. Haven't heard anything about it since then, so I don't know where it went.

Your reactions were the same as how I felt watching it the first time. (And the second and the third) It’s up there with my all time favourites. Great video, keep it up 🎉

Your editor was on FIRE!!! 🔥🔥🔥🤣🤣🤣👏🏻👏🏻👏🏻💙💙💙

The writers kissed up to the Chinese in order to get the movie released in the Chinese market.

Hexadecimal, or hex, is a base 16 numbering system, like decimal is a base 10 numbering system. There are ten digits in decimal, 0 through 9, after which you carry the one. There are 16 digits in hex, 0 through 9 plus A through F, after which you carry the one. 0 through 9 are the same in both numbering systems, but whereas decimal then proceeds to 10, hex proceeds to A (which we notate as 0xA, or commonly, with a leading zero as in 0x0A). 10 = 0x0A 11 = 0x0B 12 = 0x0C 13 = 0x0D 14 = 0x0E 15 = 0x0F 16 = 0x10 17 = 0x11 and so on. We use hex when dealing with computer code, because information in a computer is stored in chunks that are powers of two (because computers operate in binary, meaning 2 possible digits, 0 and 1), and hex is a common such chunk. A byte is 8 bits, a word is 16 bits, a double word is 32 bits. (Because of this, it's a whole heck of a lot easier to translate binary to hex and back, in your head, than decimal.) One of the early character sets is ASCII (American Standard Code for Information Interchange). ASCII has 128 different codes (0 - 127), of which 95 are printable characters. So that's 0 to 127, or in hex, 0x00 through 0x7F. So Watney positioned 16 hex numbers, 0 through F in a circle. And NASA would need to point to two hex digits to express one ASCII printable character: Your first name in the ASCII character encoding, expressed in hex, is 41 6C 65 78 20. Note that a capital 'A' (0x41) is distinct from a lowercase 'a' (0x61).

This is based on a book, and the movie does a really solid job of it. Plus, almost all of the science checks out except the dust storm strength. The author also wrote an even better book(imo) called 'Project Hail Mary', about an astronaut waking up with with amnesia that slowly learns his mission is to save earth, with similar themes and humor, but an even crazier spoilerly element I won't go into. Ryan Gosling is set to star in the movie.

Wadi Rum in Jordan was used for external scenes on Mars in filming The Martian. Korda Studios 26 kilometres (16 mi) west of Budapest, Hungary, in the wine-making village of Etyek was chosen for filming interior scenes of The Martian. It had one of the largest sound stages in the world.

Andy Weir worked really closely with NASA scientists when writing the book. So aside from a very very small number of things, everything is reasonably grounded in actual science. And then Andy was very involved in the making of the movie so while the movie takes a few more liberties than the book did, it's still very scientifically plausible

This movie is by far my favorite space movie. I saw the movie first, then read the book shortly afterward. Both are amazing.
