You can tell that Michael is older in Part 2. It’s crazy how much can change in 4 years.

I didn't even realize Elizabeth Shue played both Ali in Karate Kid and Jennifer in back to the future part 2. She played the girlfriend of two 80's icons.

I never noticed the differences between the scenes until now.

I'll always be fascinated with how they seamlessly intercut shots from the old version just to sell the fact that your watching the same scene. Such slick camera work and editing. And acting! The actors had to mimic there performances to a tee!

I can't stop laughing when the audio syncs almost perfectly and also when they de-sync completely and is total chaos.

Elizabeth's hair started blowing immediately when the DeLorean pops up 😂 Michael's hair is also noticeably different, but overall pretty damn impressive. It's a real shame they couldn't get the original actress, I thought they were a better match-up although I loved Shue's "figure self" thought she did a great job with the campy humor, considering she was coming to the series brand new.

Michael J Fox’s “I can explain” look to Jennifer is hysterical and he does it exactly the same both times

That look on Biff's face after the DeLorean zaps away into the future makes him look like a villain again (as he was in 1955).

The only major differences I can see are the recasting of Jennifer and the insertion of the joke where Doc has to think for a second about whether the future McFlys are assholes. And the Biff reaction, of course.

The first time I saw this, I didn't even realize they had re-cast Jennifer. To be fair, her part in the first movie was pretty small, and it had probably been a couple of years since I had seen it. I did realize it had been re-shot, but couldn't figure out why. Then, some years later, I watched them both back-to-back and felt like an idiot 😂!

I love the original Jennifer. Wish she would have been able to make the second one so bad. I bet it would of turn out so much better too.

Imagine if they never made any sequels. We would've had a forever cliff hanger at the end of Back to the Future.

wow, this is beyond weird. I just watched these two scenes last night and compared them. I think the first one is slightly better. Tonight I'm gonna watch BTTF Part 3.

In this scene, I prefer Claudia's acting. With all this world shattering babbling and gesticulations from Doc Brown and Marty, she has an appropriate reaction : looking in awe, open mouthed, anchored to her love interest. Elisabeth has a more cartoonish acting IMO, staring in every direction like a Tex Avery character. Claudia is also 19 in 1985, so a genuine teenager, while Elisabeth is 26 in 1989. Having late 20's adults impersonating teenagers was a very common feature back then, but it really shows when comparing the 2 versions of this scene.

I watched all back to the futures about 20 times ,, I never realised they re did the scenes and changed the actress that played Jennifer until now,,, I feel so stupid lol

Both Elisabeth Shue and Michael J. Fox doesn't look like 17 yo teenagers in the reshoot ...

I LOVE the original Jennifer, she’s gorgeous and plays Jennifer so well ✨

My family saw all three parts at the theater on Sunday afternoon, after church during the first week they came. A year or so after the last one, we all went on a Universal Studios tour and saw the set. Kids loved it. At 70 years old I wonder what happened to our entertainment industry and am sad that my grandkids did not/will not get the great wholesome experience we had. PS we never noticed the role changes until we rented all three DVDs and watched them back to back over a long winter weekend. It took nothing away from our enjoyment.

1:18 "Uh..No, no Doc...ya see, I got Claudia Wells here so..."

From Claudia Wells to Alli with an I 😂

I prefer Claudia wells

Was lucky enough to see the first one in the theatre. I still love that movie

Biff is one of the best bad guys ever.

I've watched this video on my desktop computer with the video zoomed in really close. I can see differences between Back To The Future Part I and Back To The Future Part II. Back To The Future Part I you can see it's a nice sunny cooler day with some wind blowing since you can see Claudia Wells and Michael J. Fox hair blowing through the wind. If you look at the two windows you can see it looks like decorations are hanging up. Back To The Future Part II you can see it's an even nicer clear sunny day with no wind blowing since you can't see Elisabeth Shue and Michael J. Fox hair blowing through the wind. If you look at the two windows you can see there are no decorations hanging up in the two windows. Claudia Wells and Elisabeth Shue are two beautiful women. They both played Jennifer Parker in their own beautiful way and did a great job. I never realized how much they both looked so much alike in these movies until you compare them. They need to do a reunion with both Claudia Wells and Elisabeth Shue since they both played Jennifer Parker.

claudia wells is of an beauty amazing.

Here’s my little theory about Jennifer’s change in appearance between movie 1 and 2 with continuity. So in the telltale game, Marty inadvertently messes with Officer Parker (Jen’s Grandfather) from arresting Kid Tannen’s goons in a shooting car chase and later reveals he was again inadvertently responsible for splitting Danny Parker with his love Betty. Later on when Marty is launched into the alternate 1986 with Citizen Brown and all that, Jennifer is reverted back to the Claudia Wells version of the character in this given universe, and lacks some characteristics of the version we had from Part 2 and 3. This could imply that sometime after the arrest of Kid that Danny and Betty reconciled and got married which inevitably leads to Jen, but in the Citizen Brown series of events that brought on a more strict upbringing. I like to think that because Marty changed history with Jen’s Grandma Betty in the main timeline of BTTF that when the timeline overcorrects itself from the events of 1885, 1931, 1955, and 1985 (i.e. BTTF 1) it changed Jen’s appearance and personality just a bit and synced up with whoever her Grandpa married in the past. So the original ending for BTTF 1 would be the alternate version of the timeline with no alternative ending in 1931, and the BTTF 2 intro would be the MAIN timeline with all the altered course corrections and events in tact within the time stream from anything prior to 1986. Basically Jen’s appearance from the beginning of BTTF 1 is with the Grandma Betty continuity and then by the end the time stream corrected itself and now we have the alternate continuity.

i love the part where he empties the can. its just one of those subtle yet all so true "genius" moments... so caught up in habits, so busy thinking of other things, that you overlook that what you are actually doing is utterly pointless...

the actress playing Jenifer was acting more natural in the first movie (left screen)

I wish the 2nd Marty would've bumped into Jennifer's dad in Part II as he was about to hit on Dawn Wells (which they could've easily accomplished with footage from part 1) and into Elizabeth Shue playing her own mother. That would've slightly altered the future and who Jennifer's parents were, which would've explained Jennifer's new appearance in the revised 1985

I noticed something different, I thought Jennifer aged faster than Michael. But then I found out later it was a different Jennifer.

I didn't appreciate this movie as much compared to Star Wars as a kid. But now as I've gotten older, (and watched Star Wars slip away on life support) Back to the Future is a timeless classic I hope never gets "updated for modern audiences."

1:49 is where an iconic line was born

The original Jennifer was way hotter!

White doorway is different. Plant next to said doorway is different. Windows next to said doorway have different window treatment and possibly even windows themselves are replaced. Truck is not same truck as the interior cloth is different. Tools on wall in garage are different. Cars in background on the street were different except in the reused shot when the DeLorean backs out of the driveway.

I like the way Doc says "roads" better in part 1.

Claudia was the best! I had a big crush on her back in the days!

My in-universe explanation was always that Jennifer had changed because Marty changed the timeline, so her parents never met and instead her Dad married a different woman and boom! Genetically different Jennifer.

la verdad claudia wells es una belleza de mujer, es perfecta.... la otra si esta bonita pero no hay nivel de comparacion

I'm in the Elisabeth Shue camp. I thought she was clearly better. Her reactions still crack me up. I actually wish she had been in the first one for the few minutes that Jennifer appears. I feel that the original actress wouldn't have been as good in the more Jennifer heavy part II. Claudia just didn't strike me as more than run of the mill even then. Yeah she was pretty, but I honestly feel it would have dragged part II down even more and there was already enough drama with other cast members. Elisabeth was great and proved it. She went on to have a great career, and later in her career she was even nominated for an Academy Award, back when it still meant something. Claudia . . . is doing ok.

Claudia acted like someone who knew Doc and Marty, and was used to their crazy shenanigans, so nothing they did really surprised her. Elizabeth acted like someone who had seen Back to the Future Pt. 1.

I find it interesting that Doc isn’t concerned about keeping the Time Machine a secret from Jennifer.

Nice work! Bravo.

The first Jennifer was well fitter! Wow, Christopher Lloyd says everything almost identically!! Great actor!!

Thank you 😊

"Oh crap, are you kidding me? Two dots!? This never needs to be more than one dot--the two of you made us uncertain!"

Love Docs pause for thought when Marty says “what do we become assholes or something?” in 2 😂

That’s amazing thank you.

Marty's haircut wasn't exactly the same. I just noticed that. I bet the 4 year gap before the sequel made these differences hardly noticeable

When I saw the trilogy the first time, I diden't noticed the difference. My second time I seen them I heard on the voice of Doc before they takeoff with the Delorian. Then I altso took both movies side by side to compare. You seen good differences in the backyard where the 4X4 its parked, difference on flowers and plants.

Wow, I just assumed they showed us a clip from the first movie. Crazy !!!

I didnt even realise this till a few years ago when both movies played back to back on tv haha. Then it clicked

Claudia Wells and Elisabeth Shue are both so beautiful here. They are two great actresses who played Jennifer Parker. They both look so much alike here. My favorite part with Claudia Wells was when she is standing there watching Michael J. Fox play his guitar and enjoying the music. You got to admit, she is so beautiful in that scene. My favorite part with Elisabeth Shue was when she was sleeping in the swing and Michael J. Fox wakes her up with a kiss and she is so happy to see him. You got to admit, she is so beautiful in that scene. Claudia Wells and Elisabeth Shue are both beautiful angels in their own way!

I never noticed this when I was a kid but when you watch side by side you notice it's a lot different. I mean it's the same but hand placement and delivery of certain lines is quite different. Christopher Lloyd definitely played it more toned down in the first movie. He seems a lot more hyper and the delivery of his lines is a little more intense. I love Elisabeth shue but I really wish they could have gotten the original actress back. If I remember correctly she was caring for her sick mother.

Great Scott!! 😎👍

Strange Doc in the Multiverse of Marty 😁😁🤗🤗

I find it funny that when Marty in the second movie asked Doc if him and Jennifer were gonna be assholes in the future, Doc had that one look that said, "did you? I dont remember" and then he said no while it the orignal he didn't hesitate by saying no. That's kinda funny tbh similar to how in the end of 2 and the beginning of 3, when Marty tried to convince young Doc that he came from the future which resulted in Doc fainting and Doc felt more scared and puzzled in 2 while in 3, he looked slightly more annoying by saying "what, what" right before he screamed.

One of the key differences is Doc's delivery of the line "no both you and Jennifer turn out fine..." In Part One, he delivers it quickly. In Part Two, there's this momentary hesitation as if he has to think about it. Since in the original, a sequel wasn't planned, the ending was meant to be a joke. When the sequel was written and Marty's future required fixing as well, Doc had to think about how much to tell him. It's very subtle, but the delivery of the line is important.

“Is that a flying DeLorean?”

Elisabeth Shue!❤

i really thought they used the same scenes

On the subject of Jennifer changing...If it wasn't for the fact he returned to 1985 at the same house & going to the same high school he was at when he accidentally went to 1955 and altered a few things which improved his family's lives, the chances are he would've had a different girlfriend (not necessarily a better or worse girlfriend just a different one due to not meeting at the right time being in other places) what he did alter could've easily changed his girlfriend but as he still went to the same school where he met Jennifer then chances are he probably still would’ve got the same girlfriend but it still wasn't a certainty he'd come back to 1985 with Jennifer as his girlfriend.

Обожаю фильм "Назад в будущее".

“Everything is Great”

They did a pretty good job recreating it in part 2, but it's played, shot, and cut better in the original movie. - Chris

Elizabeth may be the better actress, but Claudia was a better match to Marty. But now I just realized they made Marty slightly matured in episode 2, probably to accommodate Elizabeth

I disagree, Elizabeth Shue does a better job, look at her facial expressions/eyes reacting to doc brown. Given the tone of part 2 it fits.

lol seeing them side by side and the difference in hair length and styles is funny.

a theory I thought of the other day to “justify” this difference between the two scenes within the history of the films (I say this because almost everyone knows that the scene had to be re-recorded due to the fact that the actress who played Jennifer in the first film had to abandon the character to take care of her cancer-stricken mother): perhaps the timeline at the end of the first film had not yet completely changed, which would have temporarily maintained Jennifer's old appearance and caused Marty confusion due to the changes in his family's history , but after the Doctor took them both to the future, the new timeline may have finally taken the place of the original timeline, which I imagine may have even altered Marty's memories to the point where he recognizes Jennifer even when she appears with a different face, and perhaps this means that he received the memories of what he experienced in the new timeline as the protagonist of the film The Butterfly Effect, but in a much slower way (remembering that this is just my theory, right?) .

and the street on the left is much darker than the other

Doc are perfectly synchronized

I think it was easier for Claudia wells here is why, Claudia was the original character having done only 1 she created the character. But Elizabeth had to play both Claudia wells ending scene and the character so it’s was twice the hardest. So it was easier for wells to act the original character. Does that make sense?.

First Jennifer was so gorgeous 🤩

0:31 puzzled Marty McFly turns around and looks at their doubles! Marty: "I KNEW I heard voices!"

It all makes sense now.

Wow I didn't notice that Biff was added

0:56-Completely different time of day (or season, or both)-shadow from garage noticeably visible in 2, not visible at all in 1. In 1, Doc and Marty’s shadows are noticeably to the left.

Is was today years old when i found out there were two different Jennifers

I'll pick part 1

What’s with the wrist watch on Marty? It’s not there for the original -

I didn't even realize til now that it was two different actresses in the role of Jennifer, or that they didn't just use the same footage.

Elisabeth Shue was my crush but I have to admit that the woman in the first part is more beautiful

It bugs me that they re-shot the Jennifer-less parts of the scene, where it's just Marty. They did that with the part where Marty's parents are in the window.

1:35 Favorite part

They didn't even use the stock footage from the previous movie

Claudia Wells is pretty more Beautifull

Quem é a Elisabeth Shue ? A do 2° e a do 3° ?

I never knew the actress was replaced

Marty: What, do we become assholes or something? BTTF1 Doc: No no, you and Jennifer turn out just fine! BTTF2 Doc: (had to think for a second, remembered seeing their awful future, basically lied) Oh uh no no, you and Jennifer turn out just fine 😁

Anyone notices theres stickers on the window in one version and not in the other and the bushes are different?

Who else was waiting on the lines from Family Guy's Doc?

This reminds me of when Rick splits realities with Morty and Summer and he's the only one in sync

I had no idea these were different shoots

I always thought that it was the same clip.

In BTF 2 they neglected a lot of details, such like Jennifer's hair, is quite different in both actresses, when Doc goes out from the Delorean you can see a Red truck in the background that doesn't appears in BFT1. The shots with Marty and Jennifer have not the same angle position with the Delorean behind them.

1:10 i need fuel i need fuel LOL

I remember the original didn't have the to be continued at the end...i also remember hearing part 3 was being filmed before part 2

claudia wells too much better, sorry for the fans of karate kid girl

Doc did the best

I like more Wells' hair

The framing the two difference is out of sync,the OG Jennifer blocks the white door behind them& the Elizabeth Shue's version the door is seen all clear & more sunny in shot?.So, it must be difficult get all reshoots to match exactly to the Teeth?.
