Sleepwalker

When wealthy couple Richard and Angela visit Marion and Alex in their decaying family home, their differing social and moral attitudes create uneasy tensions. An inharmonious evening of drunkenness and sexual rivalry soon turns bloody as the guests fall victim to an unhinged attacker. Featuring a rare performance from Bill Douglas, and starring British screen greats Joanna David and Heather Page (both of whom would go on to work with Douglas in Comrades), Sleepwalker is an outrageous and incendiary mix of biting satire and bloody horror that is at once reminiscent of otherwise unlikely bedfellows Lindsay Anderson and Dario Argento.
