The Truman Show is a provocative, daring drama, and Carrey, heretofore the Silly Putty-limbed star of such lowbrow joy buzzers as Dumb and Dumber and Liar Liar, pulls off the movie's tricky leading role with aplomb.
The Truman Show is a movie and the name of a television show within the movie, both of which star Jim Carrey. This tidy little metaphysic is superbly maintained throughout Peter Weir's flawlessly executed film.
The important thing is that Carrey and the filmmakers have taken pains to give Truman that soul -- which, in itself, provides a kind of depth. In any case, it gets you to care about how it's going to end.
The movie might have been a soulless exercise without [Carrey]. With him, it has an authentic tremulousness, and also a dread, as if Pinocchio needed to take on Gepetto and Jiminy Crickett to become a real boy.
