Typecasting vs movie career

[Kam]

When I think of typecasting, I think of guys like Tony Danza or Matt LeBlanc. It's like they're playing themselves on camera.

Speaking of playing oneself...I was sort of impressed by that guy who played the founder of Facebook in The Social Network. Then I saw him in something else and I realized that's largely his real demeanor.

Actually even if they are 'playing themselves' that's not easy to do. Take a look at how many models fail at playing themselves as models in films, or singers who can't play singers, etc. Sometimes just being yourself is incredibly difficult to portray realistically in a movie.
Check out Matt LeBlanc in the showtime series Episodes. He's fantastic in it and really good at "playing himself" even though it's not really him.
