The Truman Show (PG) Director: David Weir
Although the story seems farfetched, it isn't long into this film before you start to believe it's possible. A 'perfect' town staffed with actors in a giant bubble dome, with thousands of hidden cameras, all filming the life of the one man - Truman Burbank - who isn't an actor, and accepts this artificial world as real.
His whole life from birth is shown 24 hours a day to fascinated audiences throughout the world, for whom this living docu-soap is the staff of life. You start to believe it's possible, because all the elements are already present in much popular television. Ordinary people being filmed in situ at shopping centres, or on cruise ships, have been elevated to superstardom. It is now possible to watch the life of at least one person 24 hours a day on the internet.
The step to making such a drama with an unaware subject suddenly seems small.
