Any slasher movie with a title like April Fool's Day would have to be a spoof, and this one fits that niche perfectly. Eight college chums are invited to a weekend April Fool's party held by their mutual friend Deborah Foreman. En route, the eight friends are victimized by a practical joker, leading them to expect more of the same at the party. But things take a grisly turn when "fun and games" segues into murder. At least, that's what seems to happen. While it's refreshing to see the "Ten Little Indians" routine being played out with squirting flowers and whoopee cushions rather than knives and arsenic, April Fool's Day makes its point far too early in the proceedings, then has no place to go. Kudos, however, for the spiritied Canadian cast, including Leah King Pinsent, daughter of veteran actor/director Gordon Pinsent.
