Piranha (1978)

The military hires scientists to genetically engineer a new strain of carnivorous Piranha. They called this project "operation razor teeth". The Piranha were originally designed to destroy the water system in Vietnam but of course the operation gets botched and the killer fish are loose in a American river. A children's summer camp and a summer resort become the main targets for the blood thirsty fish.
This is the first of the Piranha films and the best out of all of them. It was directed by Joe Dante who would of course go on to do The Howling. James Cameron will go on to do the sequel in 1981 where the fish will mutate once again and fly. Then in 2010 we got the Piranha remake in 3D. All of the Piranha films are dumb-fun but this one is by far the best. It has Paul Bartel as a summer camp councilor who bullies around young girls but he wont be stalked by a dude in a hockey mask. Instead he will be ripped to shreds by the Piranha. We also have Dick Miller (the king of cameo) and hes always great to look at. Barbara Steele also shows up, not looking so great in 1978. The movie also throws in some gratuitous nudity for good measure and I find it completely brilliant that the Piranha eat the bikinis off of swimming babes for some bare boobage. We also got some nice gore here and there. I'm not sure who decided that the fish should make such an obnoxious sound when they attack but you might need some ear plugs. So stuff your ears with some cotton balls and enjoy a bloody outing with Piranha.
