The Jim FUCKING Carrey Category
Some actors act. Jim Carrey commits crimes against subtlety. This category is for when you want elastic-face chaos, emotional whiplash, and jokes that should not work but do. He is so good I can't choose "only 3 movies". He is the main reason for the presence of "Honorable Mentions" on this website. He is a genre. Deal with it.
