Battle Royal is an interesting one, based off manga of the same name, its about a group of students who are thrown into a remote island and have to kill each other to survive, each are given a weapon at random, some are useful like a gun, some are just outright useless, like a paper fan. All students also have an explosive collar attached, any attempt to leave the island or trying to forcibly remove the collar will trigger the explosive. The movie is released at 2000 if I remember correctly, it's quite gory at it's time.
