The Movie: A group of college friends decide to spend their spring break relaxing, getting drunk, and having sex at their rich friends mansion that is located on an island. Unfortunately though, there is a mysterious killer on the island as well who is stalking the group and picking them off one-by-one in a series of gruesome ways. The Ending: With a title like April Fool's Day, it's no wonder that director Fred Walton's seemingly routine '80s slasher flick would hinge on a well-timed Gotcha! moment. The first time you watch the film, though (assuming you've done so before reading this, of course), its hard to imagine the idea that every decapitation, castration, stabbing, and throat cutting has been a hoax, all imagined by Muffy (Deborah Foreman), the host of the getaway. What appears to be a straightforward horror movie is actually a very dark comedy, not to mention one of the more ambitious killer-on-the-loose flicks from the decade known for its slasher overload.
