This sounds like it could be fun. How do you plan to judge what happens? Obviously people would generally rather live than die, especially if they're having fun with the character. So will the ability to survive the traps be dependent on how clever we have our characters act, or some sort of randomizer, or GM whim, or something else?
Would you consider having people play multiple characters? Usually I'm not a fan of that in group games, but in this setup it would allow a stream of character deaths while delaying cutting out players.
Do you expect there to be more of a sexual element than there was in the movies, or would you prefer the game be focused mostly on the death and gore?
