Time Out review:
Truman Burbank is beginning to wise up. People seem to listen to him, but they never really connect; he feels trapped in a job he doesn't care about, a marriage he doesn't believe in, and a small island community he's never been able to leave. It's as if his life has been pre-programmed from the start: as indeed it has, for Truman is the unwitting subject of television's most audacious experiment, a real-life soap following one man from birth to death. When Truman (Carrey) appeals to a higher power, he's actually addressing the show's omniscient creator/director, Christof (Harris). The best comedy since Groundhog Day - better, even, than that - this is more than just a savvy and ingenious satire on media saturation, it's a moving metaphysical fable. One movie you can pronounce a modern classic with absolute confidence.
Here (and above) is the trailer.
