One of my favorite shows is Alone. That's the show where they dump you off in the Arctic and just wait until you go insane. I've been thinking. It would be fun to do something like Alone, but with special effects to really mess with the survivors. Like have a Bigfoot walk through their camp, a visit from space aliens--that sort of thing. You could really mess with these people. Plant a dead body on the trail, then have it disappear. That sort of thing.
