Which actor/actress are you unable to dissociate from one of his/her role?

Everyone from the Friends cast

For me, it's David Tennant as The Doctor. It was very strange seeing him in Good Omens.

I never watched an X-men, nor the old Dune, so for me Patrick Stewart is Jean-Luc Picard.

Agree! When I see him in other things I'm like "oh hai Picard"
- Voice of Avery Bullock in American dad. In Picard show, is his age caught up to him and he looks super disinterested and tired

Peter Lustig. But he also played himself and had full power over his show.

Martin Freeman as Bilbo

Til Schweiger as his arrogant asshole self

Jason Alexander is cemented in my memory as George Costanza.

Art Vandelay.
- Carthwright.
Duckman
Even when he’s a lizard bartender on The Orville
- Or the genius alien in voyager, think tank episode. I think Seinfeld is worst off though, it make sense considered what kind of person he is nowm

Jaleel White is forever Steve Urklel.

Alfonso Ribeiro is Carlton.

Alfonso Ribeiro will always be FADDER!

SPEAK UP, WE CAN'T HEAR YOU.

Sarah Michelle Gellar will always be Buffy Summers to me.

I somehow missed Buffy growing up, so my first exposure was of her as Daphne in the Scooby Doo movie.

I think now that I've watched a lot of Buffy, those two balance out for me.

Roger Moore as Bond - he wasn't the best Bond, just that he played that character for like 30 years, starting with The Saint in the 60's.

Once you see him there, it's hard to see him as anything else.

William Shatner and Leonard Nimoy as Kirk and Spock in the early Startrek films and series.

Same for Brent Spiner as Data.

Lucy Lawless will forever be Xena the Warrior Princess.

She was great in BSG, although she didn't get many episodes.
- Spartacus too.

Say my name

Hal.
- Tim Whatley

Danny Trejo is of course Machete (or Uncle Machete to the Spy Kids) - even if he does occasionally rangle Rancors or other roles.

(But only when I can see him. I had no idea he had that many voice roles until looking him up just now)

Norman Reedus with forever have "and the funky fetus" after his name because of Death Stranding.

For me he's always gonna be a Boondock Saint.

Sarah Jessica Parker is Carrie Bradshaw.

Since 1995, I’ve always associated Ian McKellan with his iconic portrayal of Richard III.

Which colored my impression of Lord of the Rings a bit.

Now is the winter of our discontent, but that is not for us to decide....
- My kingdom for the lord of all horses!

Idris Elba and Dominic West will always be Stringer Bell and Jimmy McNulty for me.

Mac from IASIP. Saw his picture with his son and immediately got thinking 'place away this psycho from a child'

His plastic surgery made him look all strange, and he's pretty pretentious as a person too, and addicted to the Hollywood lifestyle. If you watched the interviews he given over the years you will know. Associating himself with Ryan Reynolds because he wanted the ted lasso fandom, and a famous retire American football star.

Even his fans on the isaip subreddit was thrown off by Rob and Kaitlyn appearances
- All I could find was that he lifted his butt. Honestly, it's the most Mac choice and I can believe in whatever I want at any given moment based on the argument I'm trying to make

Easy... Arnold as Terminator.

Ian McKellan is Gandalf, and I will fight anyone to the death who disagrees.

Magneto?
- While he did a decent job with Magneto, I would say that his Gandalf is far more recognized.
He has done quite a few iconic roles though
- True, but I would argue that none are as widely recognized as Gandalf.

Ryan Reynolds Van Wilder

David Dastmalchian will always be Joker's thug/Fake Cop from The Dark Knight.

Kind of obscure, but Brits of a certain age will always think of Alan Dale as "Jim from Neighbours". Another one being Guy Pearce as "Mike from Neighbours". Pearce has had a slightly bigger career than Dale maybe, but you've almost certainly seen them both in popular movies and TV shows.

Excellent answer, particularly Alan Robinson/Jim Dale. Or whatever :-)

Joe Rogan is Joe Garrelli in News Radio

Young Guns will forever in my head have Jack Bauer in a leading role.

You mean Lost Boys vampire gang leader David?

david thewlis' role in fargo! /season 3, just so good!

Dude, Walter, Donnie and the Jesus from The Big Lebowski. Whenever I see Turturro play any other role, he's so bland and normal.

For me Turturro will always be Pete from Oh Brother, Where Art Thou.

“Do not… seek… the treasure.”
- I think if you watch Severance, he does a really good job of changing your perspective, because I had the same feeling going into Severance, and now I feel different.
- Roland T. Flakfizer is ballet.
- We thought… you was… a toad
  
  What??
  
  We thought… you was… a toad!
  
  SHH!
- Such a great movie.
John Goodman will always be Dan from Rosanne for me. And Buscemi will always be Mr Pink 😁

Machlenny, Glenn, Kaitlyn from isaip, they just aren't good outside of the show. Also rob is pretentious as fuck. Typecasting is pretty much a curse for people like these

Claire Foy as Lady Percy in the Upstairs, Downstairs reboot. Seeing her play the queen just felt so wrong, lol.
