I was in hospital at the time he passed away but I can tell ya he's been in so many great movies such as Aladdin (who doesn't love that genie?), Flubber, Jumanji, Good Will Hunting, Mrs. Doubtfire, The Birdcage and Happy Feet (and its much worser sequel), where he did two characters in that film (Ramon and Lovelace) nonetheless.
Oh, and there's Robots too. I always loved his performance in that film as the voice of Fender. But yeah no wonder why his death hit many hard, it was mainly due to his personality and of course all the amazing films he's been in.
Apparently he was suffering from Parkinson's at the time he killed himself, that's really interesting. I wonder if he had something against the condition that made him not want to live with it or something.
Still, RIP to a great comedic acting legend.
