I was a Robin Williams fan. But I'm definitely not up everyones ass about him dying. It's sad, but it's always annoying when you see so many people only acknowledge someone when they die. Robin Williams was really funny, he was also over bearing at times. If you think about it that over-acting, over-bearing was just covering up what was wrong inside.
I liked Mork and Mindy, The World According to Garp, Good Morning Vietnam, Cadillac Man, Hook, Aladdin, Toys, Mrs. Doubtfire, The Birdcage, Jack, What Dreams May Come, and One Hour Photo.
Hook, Mrs. Doubtfire, and The Birdcage are classics...
If you're unfamiliar with his more serious roles, One Hour Photo, What Dreams May Come, and his episodes on Homicide: Life on the street, and Law and Order: Special Victims Unit are really good.
