"Battle Royale" (2000)
Tagline: Could you kill your best friend?
Director: Kinji Fukasaku
The plot: In a twist on "Gilligan’s Island" that could only come out of Asian cinema, the Japanese government captures a group of junior high students and forces them to kill each other until only one remains. (Available for years only as an import, the movie was eventually for sale at Amazon.com.)
The shock: Imagine “Lord of the Flies” with Japanese schoolgirls…and crossbows.
