I have seen this movie, but you cannot see it or buy it in the US, don't know about other countries. Being in Japan I have seen it a few times with friends, and yes it is as fucked up as it sounds. A class from any school in Japan is chosen at random, they are then taken to an island, knocked out so they do not know where they are when they wake up. They are told they must all battle eachother and kill eachother in 3 days, the last one alive wins. They are also all wearing collars that will detonate if they are in illegal zones, or if there is more than one person alive at the end of the three days. So you cannot just wait it out, because you will just blow up. Each person gets a bag at random with various supplies, ranging from an uzi to a frying pan...i am not kidding one guy gets a frying pan. It is really graphic and the content is hard to take in because it is very well done. To imagine this ever actually happening is very troubling. Many people in Japan do not agree with this movie, with good reason; however, i think if you are old enough you should definately see it just see what it is like.
