Robin Williams did an excellent job on law and order SVU, God rest his soul.

Ludacris should’ve at least been an honorable mention. He was EXCELLENT during both his appearances as Fin’s diabolically intelligent step-son Darius

*Olivia's hair changing is the best*

Carol Burnett gets my vote for #1. Her performance was bone chilling. The way she just casually tossed her "nephew" Chet under the bus still sends shivers down my spine.

Robin Williams was such an underrated dramatic actor.

Good list but missing one. Jerry Lewis. He played detective Munch's homeless uncle. Fantastic performance

Robin Williams was a rare comedian who could also do serious dramatic roles and excel in them. What a loss, I'll always miss your incredible humor, Robin.

Rafael Barba is my favorite character next to Liv. They had the best chemistry period.

We need a part 2 because their is so many more who didn’t make the list

The episode with Jennifer Love Hewitt was amazing! She's awesome!!

Spoiler alert: Robin Williams' character Merritt Rook in "Authority" is one of my favorite villainous roles. A sound engineer by trade, Rook goes on a crusade against authority figures, even going so far as to insult lawyers in open court (the clip you see where he talks about his bail money includes a scene with a quote "Why would I want some hack public defender?" or something like that). While Rook himself doesn't commit many of the crimes, his profession allows him to disguise his voice, manipulating several other characters into doing it for him. He's brazen and arrogant - he puts up his own apartment as collateral for his bail. He acts as his own attorney, he outright accuses the tech guy of manipulating the image, and he even cries out "Thank you!" to the jury when he wins his case. The truly creepy part, and I still get chills to this day watching it, is the final ten or so minutes. We find out that his disdain for authority was pushed over the edge when his wife and baby died in labor because he trusted the word of an alcoholic doctor that there wouldn't be any issues, but the doctor made a mistake. Rook was hellbent on getting revenge, so he disguised his voice and constantly harassed the doctor until he committed suicide. He kidnaps Det. Benson and rigs a room to look like it has explosives in it. He makes Stabler shock her - a modification of the infamous Milgram experiment - in order to save her life. And he threatens that the shock is real, and if Stabler refuses to do it, he'll increase both the voltage and the length of the shock. One of Robin Williams' best performances I ever saw, and I have to agree with this list for once.

Pablo Schreiber should defiantly be on this list! His portrayal of William Lewis is amazing! Not to mention he came back as that character for many episodes! Amazing.

This should be called best guest appearances, not cameos

Marcia Gay Harden belonged on the list and not as an honorable mention. Every episode she did was incredible, esp RAW. To watch her play a racist while undercover and then find out who she really was, it was just incredible

Sarah hyland should've been on this list! Her role as the chess champ that killed a child prodigy out of jealousy was absolutely brilliant!

Martin Short’s cameo was mind blowing. So did Carol Burnett’s, especially since Matthew Lillard, whom I love was also in it. And Robin WIlliams has never done a bad acting job he was amazing.

um wow Ludacris should have def been on this list. His character was incredibly evil and he played it well.Also Rose McGowan deserved an honorable mention at least.

Martin Short's cameo completely changed my perspective of him. I can no longer see him on tv or in a movie without hearing go "That was the sex I ever had." in that gravely voice he used on the phone.

Mariska Hargitay sure knows how to rock a pixie-haircut.

SVU was perfect at taking comedians as well as former Disney/child stars, and putting them in roles that really tested their acting abilities.

Whoa, did any one else catch A.J Cook in the Jeremy Irons scene? Just pause at 3:20 if you didn't.

We need a part 2 of this list because there are so many more than just 10 actors/actresses who deserve to be recognized for their cameos .

Jill Scott, Matthew Lilliard...there definitely needs to be a Part 2!

Lou Diamond Phillips played one of SVU's most chilling villains. Still creeps me out.

Lou Diamond Phillips deserved an honorable mention.

Mathew Lillard (from Scream and Scooby Doo the movie) in the same episode as Carol Burnett

Leslie Caron’s guest star performance in Season 8, Episode 3, titled “Recall”, is gut-wrenching and powerful. She more than earned the Emmy she won and it is my favorite SVU guest star performance. She made me cry.

Definitely need a Part 2. Joan Cusack was great and that was a great episode with all the twists and turns.

Really, no Sarah Hyland? A really underrated performance as Jennifer.

The ludacris one was my favorite

I think it's safe to say that a follow-up to this list is in order.

Shout out to the Matthew Lillard guest appearance on that same episode with Carol

Ludacris should of been an honorable metioned to.

There have been so many amazing cameos over the years. John Ritter should have definitely been on this list, along with Marlee Matlin.

You should do a top 10 list of SVU villins, with William Lewis (play by Pablo Schreiber) at the top of the list. Best villain that show has ever had!

Forgot about Pablo Schreiber aka William Lewis he was phenomenal always beat the court system and all. Like he was smooth with it

SVU is one of the best quality series on tv, and has been consistently. I have seen a lot of these episodes, it's great that these actors get casted, they did a fantastic job. John stamos played a disgusting creep very convincingly

Robin williams was a Gem in his ep And to this day I want to know if he got away 😂😭

I’ve always been fascinated by what intensely phenomenal dramticians that comic actors can be. Their jokes hide the pain of their early traumas & acting in dramatic roles allow them to express their inner pain. Their performances can cut you to the core. RIP Robin Williams ❤️🌹🕊

Ludacris destroyed the whole svu. He was amazing. That whole episode was one of my favorites. Robin Williams was great too. Fred Savage was creepy. Bob Sagat was crazy.

Surprised Angela Lansbury wasn't mentioned. She was in the episode with Alfred Molina. I guess it's already time to work on part 2?

AJ cook from criminal minds fame was in that episode with Jeremy Irons

Isabelle Huppert belonged on this list big time (Season 11 Finale, "Shattered"). It was a rare treat for American audiences to see one of France's two greatest living female actors (the other being Catherine Deneuve), especially on a commercial network! I'm sure many folks had never heard of her, but if you thought her role as a distraught mother was explosive, check out Claude Chabrol's "Story of Women" or Michael Haeneke's "The Piano Teacher" where she's at her finest, or even Michael Cimino's epic western "Heaven's Gate".

Jeremy Irons tricky role was turned into an outstanding performance.

I still miss Robin Williams.

What about John Ritter?

What about Richard Thomas who played John-Boy on The Walton's? He did a great job! 👍👍

Ludacris, John Ritter, and a very unrecognizable Jerry Lewis should have made the list. Their performances were amazing.

Favorite TV show of all time

John Ritter and Henry Winkler should have been on this list!

I feel like y’all SERIOUSLY need to do a part 2 to this. Ludacris, Dean Cain and Rebecca DeMornay deserve a nod! So many great guest appearances to name!

Cynthia Nixon is my fav, 110%. That episode is just simply amazing.

Great list but you missed the best one; YES even better than Robin Williams. May I introduce you to: John Ritter. His performance deserves recognition 🏆

Ok Williams and Nixon legitimately scared me and I LOVED IT! They were both enigmatic and darkly magnetic while encapsulating the sense of dredd and villainy the show casts on its antagonists

WOAH WOAH, WHERE IS ELLEN BURSTN AS ELLIOTS MOM?

You forgot John Ritter, killed his wife's baby. And Brittany Snow who was a bipolar highschooler.

What about Mark-Paul Gosselaar? On one SVU episode, he played a completely irredeemable scumbag. I believe the character's name was Zack Morris.

Robin Williams was also fantastic in an episode of "Homicide: Life on the Street." He played a tourist to Baltimore whose wife is murdered.

I loved the episodes with _Emily VanCamp_ and _Julie Bowen._ Those performances were amazing, and the fact that Emily's character remains the only female character to successfully break the two-way glass mirror in the interrogation room with her bare hand is extremely cool. Also, the twist in the episode with Julie Bowen was fantastic!

Jennifer Love Hewitt was great in this episode, but James Legros was good as well. You should also included Jerry Lewis & Ellen Burstyn. She was great as Elliots troubled mother.

I miss Jerry Orbach. Would've loved to have seen him reunite with Jesse L. Martin on The Flash.

Now do a top ten best Criminal minds cameos

I love this show... Eric McCormack's performance was spine-chilling. Knowing him from Will & Grace, he's miles from that role. He really should've been on the list instead of honorable mentions.

None of these are cameos at all! They are all actual "guest-starring" appearances.

I love this show. As a wrestling fan, I find enjoyment watching SVU on the USA Network way more than anything WWE has put together recently.

What about Fred Savage? He was super creepy.

No mention of Mike Tyson? His appearance on this show actually gave me some respect for him ab a performer.

how could you guys forget Micheal Shannon. The man delivered an amazing perfomance

No way Robin Williams! Got to see that one. He is one of my heroes.

Robin Williams even got away in the episode he was in! R.I.P. Robin.

Even as a criminal portrayal in SVU Robin Williams was full of charisma.

i know that Mickey Hargitay (Mariska's father) appeared in an episode share a scene with his daughter

Saw Robin Williams in the thumbnail and clicked immediately.

To this day, 'pure' with Martin Short is my favorite episode. His character was a great leap for his abilities, and his dark turn is something I didn't even think possible for him, let alone anything I ever saw coming. Perfection.

My favorite show and I love the celebrity cameos, the acting is usually so good and spot on. It's great to especially see people who are normally comedic do drama; it's like a whole new world. Also, is the guy with Carol Burnett Matthew Lillard? Because it looks a lot like him.

That Robin Williams episode still gives me chills. I miss him everyday. 💔

Whoopi’s episode was so real!!! When she went off in the court room on the stand about how overwhelmed Social Workers are... I felt that!!! They have no idea the amount of cases Social Services workers receive!!!

Cynthia Nixon was my all time favourite cameo as Janis Donovan. The scene where she shows up at Stablers house with his wife there was so chilling. You couldn't tell whether Janis actually had Dissociative Identity Disorder or pure Psychopath using the idea of D.I.D. to her advantage.

Thank you for your excellent compilation of Spectacular performances on LAW & ORDER: SVU

where's Henry Winkler, who's best known for that one episode of Law & Order SVU?

Finally a list I can get behind! DUNDUNN!

Robin's performance was so chilling in that episode. He channeled everything he brought to _Insomnia_ and _One Hour Photo,_ and then some. The scary thing is we don't know whether or not he got away at the end.

Always enjoy your 10 best lists!

Carol Burnett and Mathew Lillard

John Stamos’ character was so perfectly sleazy on SVU

Robin Williams played a grieving widower in Homicide: Life On The Streets in its second season. His Homicide guest appearance was more phenomenal than the villain of the week role he played on SVU.

I really hope there's a part two for this lists because there was so many great SVU cameos like Ludacris, Sarah Hyland, Brad Garrett, Brittany Snow, Kathy Griffin, Tony Hale, Bradley Cooper, Abigail Breslin, Elizabeth Banks, Amanda Seyfried, Ian Somerhalder, Milo Ventimiglia, James Van Der Beek, Miranda Lambert, Chloe Sevigny, Rose McGowan, Melissa Joan Hart, Lili Reinhart, Fred Savage, Lynda Carter, Michael K Williams and so many more

Love them all and especially Debra Messings appearance

Amy Smart and Ludacris were amazing too and deserve a spot on this list.

Only Law and order SUV that I really love is when Chris meloni is playing on the show

Now I need to watch more SVU!!! I love that show!!!

I miss Robin Williams even more now... 😔

There needs to be more Top 10 SVU lists

After 20 years this should have been top 50. Really to many great performance. I’m adding Noel Fisher to the list. Season 10 Dale.

So many really good guest stars throughout the L&O history. I rewatched X-Files a few years ago, and was amazed how many up and comers were on that as a well. Funny you do think about them at the time, first run. It was only as I got into re-runs.

These were all fantastic performances but a few were overlooked. Henry Winkler had a good role in episode as did Martha Plimpton and Mary Steenburgen and recently Brad Garrett had a good 2 episode arc. And Anthony Edwards was good on recent episode too

I think Martha Plimpton should have been added.

Good video WatchMojo!! Sometimes you do put out great content! LOL

Good list. It's interesting to note that practically half of the cast of Modern Family have had guest appearances on that show, as well as most of the cast of Meloni's former show Oz and the original Broadway cast of RENT. I would also like to have seen Sara Gilbert on the list, at least as an honorable mention.

I'm sure this has been brought up before, but how are these cameos? A cameo is when a person makes a special appearance as themselves, or as a character they've played before, usually for a short scene. Cambridge Dictionary defines a cameo appearance as, "a brief but noticeable part, esp. in a movie, television program, or performance in a theater, usually by someone who is famous." These are just famous people who took on another gig as actors appearing in GUEST roles, not as cameos. Think about the movie Zombieland, while his part in the film was longer than a usual cameo, the fact Bill Murray played himself in the film, still makes it a cameo. For the record, I loved each of these episodes, and can never forget Robin Williams, ever. He died on my birthday, and as one of my favorite actors and comedians of all times, it's a bittersweet day for me now. How someone could paint such a cheerful mask outwardly, yet be so inwardly torn apart is amazing. It just goes to show you how gifted an actor he really was.
