Me, Myself, and Irene

Carrey is Charlie, a Rhode Island state trooper whose split personality (one meek and mild-mannered, the other an out-of-control sociopath) is controlled by medication, which he loses when transporting crime suspect Irene (Zellweger). Both sides fall for the girl and declare war on each other. Carrey's verbal and physical acrobatics, along with the Farrellys' patented gross-out scenes are as hilarious, and joyfully disgusting, as you'd imagine. And if you're into that kind of thing, you'll not be disappointed, but the movie shares the lead character's ailment: it has another side. The romance between Charlie and Irene can't keep up with the energy of the comedic scenes, especially the ones involving Charlie's three Mensa-candidate, African-American sons, who almost steal the movie right out from under him (who'd a thunk it?)
