Robert Downey Jr., he played his role really well in Iron Man, and I seriously wouldn't have guessed it was him in Tropic Thunder. XD
Also Johnny Depp, he truly becomes that character, you wouldn't even recognize him if you saw him in one movie, and then watched another with him in it. Alan Rickman portrays Snape from Harry Potter really well, it's funny. He's a good actor besides that too, but I haven't watched much.
Jack Black was really funny in School of Rock and Kung Fu Panda. Comedian-actor sort of thing.
Christopher Lee- he played Saruman Al Paccino & Robert de Niro nuff said. David Caruzo (many believe that he isn't even an actor, but i think he is good)
@ Zootsuit_riot. DUde! Christian Bale! You forgot Equilibrium! Shame on you! Ummmm, hard one. Adam Sandler. Happy Gilmore...I can't even think of that show without laughing...
But I have to add a movie to my favorite movies by Denzel Washington. The Taking of Pelham 123! That was an amazing movie. Both Denzel Washington and John Travolta did an outstanding job.
Morgan Freeman. Amazing actor, best movie he was in was The Shawshank Redemption Tom Hanks. Really good actor and can play any role, his best movie was Saving Private Ryan, and Forrest Gump
