As illustrated in the clip above, the U.K.'s Space Cadets was a pretty unique show. Contestants were made the believe that they were being sent up into space for five days, when in reality they were just hanging out in a fake spaceship on a soundstage that had been designed to the last detail; it was like Candid Camera, only in "space," if you will. It all culminated in a very elaborate hoax that cost the network about £5 million. Worth it?
