The Truman Show is about Jim Carrey not knowing that his life is being secretly filmed, and somehow becoming a huge reality TV star without acting like a jerk-faced shit-waffle. You know, typical Hollywood make-believe.
Obviously, the most implausible part of the whole thing is that a TV network would be allowed to essentially hold a guy hostage under false pretenses. There are laws against that, no matter what wacky part of the world you happen to be in. Even Japan.
Uh … right? JAPAN?
In 1998, Japanese comedian Nasubi was told he was trying out for a potential new reality show for which he would be locked in a room and not let out until he made $10,000 by entering sweepstakes contests via mail (at the time, sweepstakes were kind of a fad in Japan). It was also how he was supposed to feed and clothe himself – by winning contests for food. Oh yeah, and he was naked at the beginning.
