The concept of a world in which people are forced to kill each other as part of some mass-entertainment game pops up in sci-fi movies ranging from swinging '60s Italian thriller The 10th Victim (seriously, check it out!) to The Running Man to the Hunger Games series. While I was massively tempted to include The Hunger Games as my pick here, I’m instead opting for Battle Royale, the ultra-brutal 2000 Japanese action-thriller directed by Kinji Fukasaku.
In Battle Royale, one school class is chosen each year to participate in a massive island-based “game” during which students must kill each other until only one remains. This is done with the aid of weapons (one per student) that can range from a gun or crossbow down to a paper fan. Students must also travel from area to area to avoid "danger zones” (which result in immediate death). And if they refuse to cooperate? They get killed by way of an explosive collar,
As dystopian futures go, one in which adults kill children (or force them to kill each other) in order to maintain control ranks pretty high on the “places we wouldn’t want to live” scale.
