APRIL FOOL'S DAY   (1986) Suspense/Horror When wealthy Muffy St. John (Deborah Foreman, VALLEY GIRL) invites her college friends up to her parents' secluded island home for spring break, they all arrive expecting a weekend of sun and sex. Things are fine at first, but when one of the guest goes missing, the weekend takes a turn for the worse and only gets more horrible from there. But as bodies begin to pop up left and right, the guests have to remind themselves that Muffy always was a big practical joker--the trouble lies in trying to determine what is real and what isn't! A who's who of 1980s teen films--including Amy Steel (FRIDAY THE 13TH 2), Clayton Rohner and Deborah Goodrich (both of JUST ONE OF THE GUYS)--leads the cast of this gory, darkly comic cult favorite. CAST Deborah Foreman, Griffin O'Neal, Deborah Goodrich, Clayton Rohner, Amy Steel DIRECTOR Fred Walton
