Over the Edge is my favorite "kids gone bad" movie of all time. Released in 1979, it was based on a newspaper story, and follows a group of teenagers growing up in a planned community where there is nothing for them to do. Being kids, they turn to all the kid-evils: Sex, drugs, rock'n'roll, vandalism, violence, and some fashion crimes that could be pardoned due to the era.
One of the teens is killed by a police officer. Then, things go from bad to worse, as the teen horde traps all of the parents and authorities in the school while they destroy and burn stuff.
Matt Dillon co-stars in his very first acting role, and he is so young that it's almost painful to look at him. Other than Matt, most of the other actors didn't go on to do much, and many of the extras are actually real local teens that the production crew found. There's an authenticity to the movie, and a deep and realistic nihilism and subversion, that I just love.
Also, this movie was the inspiration for Nirvana's "Smells Like Teen Spirit" video. It doesn't get much cooler than that.
I need to go set a dumpster on fire.
