Peter Weir (“Fearless” and “Witness”) directs funny man Jim Carrey in this not so funny oddity. Carrey stars as Truman, a man with the ideal middle American existence, until he realizes something about his friends, family and job isn’t quite right — even though it takes him thirty years. It turns out Truman is really the unwary star of a “Real World”-type TV show where everyone else in his little enclave is an actor in on the gig. What Weir and Carrey come up with is a big hearted version of “Logan’s Run” or “Dark City.” Carrey doesn’t break off into outrageous physical comedy bits as fans might hope, and the film does take a while to find it legs, but there is something rewarding in its quirky demeanor.
