This sick little horror film from British gore/exploitation director Pete Walker finds a group of actors summoned by an anonymous producer to take part in a gruesome Grand Guignol play being staged at an isolated resort, only to find that their characters' elaborately staged theatrical deaths are designed to do them in for real. It is revealed that their unseen benefactor is a former stage performer, driven psychotic after catching another actor in bed with his wife, who now seeks symbolic retribution against all actors for their immoral behavior. Though not quite as sleazy as some of Walker's later work, this is still fairly gruesome stuff. The same theme gets vastly superior treatment in the following year's Theatre of Blood, featuring a tour-de-force performance from Vincent Price.
