How These Roles Differ from the Usual: Dramatic turns and villanous portrayals from an actor normally doing comedy.
I think for every bad Robin Williams role, there's a good one. For every RV, there's a Good Will Hunting. For every Man of the Year, there's an Awakenings. I don't like most of Robin Williams' comedy roles. I liked him in Aladdin because I didn't have to see him. The only comedy movie I liked him in is Mrs. Doubtfire. And maybe Jumanji. I think most people know him as a comedian though, which is why I put him in here. He has tremendous talent when playing dramatic roles or as sociopaths. I don't know about other people who saw it, but his character in One Hour Photo scared the shit out of me. His role as the villain in the Al Pacino crime movie, Insomnia, is subtle but builds up to something intense.
Then there are his drama roles. Here's some trivia for you: whenever Williams has to do a dramatic role, he grows a beard (I don't know if this includes Jumanji heh heh). His Oscar-winning performance for Good Will Hunting will always be his tour de force performance for me, however. I can't find words to describe what that character made me feel and I really wish Robin Williams would do more dramatic roles instead of letting himself run crazy in shit like License to Wed.
