Robin Williams has been in a ton of movies by now, and I know some people find him a bit grating, but I personally don't really mind it too much and I even like that he is that way because it just makes it even more surprising when he is in a more serious role due to the huge contrast in personalities. That said, my favorite performance and movie of his is still one of the silly ones which is Hook. I was very young when I saw that movie, and even then I remember being skeptical when I found out Peter Pan was going to be played by someone older, but after watching it I found the story to be pretty good and overall I think the movie was pretty well rounded and well structures. Ever scene had a reason and it didn't get boring for a second, and I now think Robin Williams was perfect for that role and few others could have done it justice as he has. How about you guys, which Robin Williams movie is your favorite? Mrs. Doubtfire or Aladdin, perhaps?
