Me, Myself & Irene (2000)

Charlie, a policeman, suffers from a personality disorder that divides his persona into two different facets. When someone provokes him too much, his alter ego Hank takes over. One day, Charlie is assigned on a mission to find a woman, Irene, apparently a fugitive from the law. But when Hank gets the upper hand, everything spirals out of control. An amusing comedy with sharp humor and scenes in which Jim Carrey steals all the show. If you like crazy comedies, this one is for you.
