Old School and School's Out

It's girls vs. boys. There's a nice similarity in the classic containment devices for both titles, while the girls punk it out and the boys keep it serious.

Old School is about a New England prep school in the 60s, where the boys compete in a writing competitions to grant them an audience with the great writers of the day.

School's Out is a retelling of Lord of the Flies where the island is actually the classroom of a middle school. After a teacher commits suicide, the substitute teacher slowly comes to realize his class is a creepy gang that all the other teachers are terrified of.
