Friday the 13th (1980)

With Friday the 13th (1980) Hollywood finally responded to the growing success of indie slasher movies with a big-budget version that would launch a thousand bloody machetes. The movie introduced gore-obsessed audiences to a new anti-hero in Jason, as well as his tragic origins at Camp Crystal Lake. If Jaws (1975) made you scared to go into the ocean, well, this made you terrified to get it on with your teenage hottie, as nookie inevitably led to the carnal couple getting eviscerated. While Jason and the gang didn't make it safe to go skinny dipping, at least they insured that scene would be included in every summer movie. Friday the 13th is far from unlucky, especially when Kevin Bacon brandishes a bulge in his blue Speedos. Bacon makes everything better!
