Did You Know?


Trevor Harris is listed in the credits as playing "Doug" but since he's never referred to in dialog by that name, he may be hard to spot. Doug is the young man who comes into the locker room for a late shower. The irritated Coach tells him to make it fast because he wants to lock up. In the shower, Doug trips, falls, knocks himself out, and is attacked by leeches, one of which enters his mouth. Later, Doug stumbles into his dorm room, obviously in distress, and vomits a leech into the sink. See more »


The wires dragging the leeches across the floor can be clearly seen in several shots. See more »


Coach Foster: As far as this team is concerned, this is not a democracy and I am the President of the United States of Your Ass!

Wow there are some hotties in this movie. As a young gay man and a horror movie buff I've always appreciated Decateou's films. There obviously not meant to be taken to seriously. But they're always a lot of fun. This one features less homeoertocism than the others and still doesn't deliver on a good hookup scene or even a kiss. But there are tight, buff, bodies everywhere with the most beautiful faces attachted to them check out Jason(I think I'm in Love). And as far as the movie goes, it's not half bad. Sure there's some cheesy dialogue,spfx and plot developments. However,these things add to the overall fun of the film giving it an 80's horror flick type feel. Now before I begin a film synopsis may I say that this a huge step up from the other fare Decateou has directed. The acting is about average, the direction is tight and the filming is stylish. And for all those bashers out there watch the other flix before tearing my just opinion apart. So it's like this, There's a swim team who takes steroids and hang out at a leech infested lake. The leeches bite them and mutate into giant super leeches that kill off members of their clan one by one. There really isn't a main charachter and no one is really all that developed. But his charachters have slightly more depth than your average teen thriller. They have moral dilemnas and in most cases are fully redeemed before meeting there untimely fates. So no matter whats your thing you curious guys out there and girls there are alot worse ways you could spend an evening.
