One Dark Night

The first sixty-or-so minutes of this undeservedly obscure horror film, when we're introduced to a fairly typical group of prankish teens, is unremarkable. However, the film offers a memorably horrifying climax that's well worth hanging on for: As the kids are setting up an elaborate practical joke in a mausoleum, a supernatural force causes numerous corpses, in varying stages of decay, to leave their coffins and pursue the now-terrified pranksters through the dark corridors. The film contains no gore (which is unusual for a horror movie of this period), but if your tastes run to ambulatory corpses it really delivers the goods. By the way, the film's shooting title was "Rest In Peace".
