Peeping Tom

Released 1960
Stars Karlheinz Böhm, Moira Shearer, Anna Massey, Maxine Audley, Brenda Bruce
Directed by Michael Powell

A frank exploration of voyeurism and violence, Michael Powell's extraordinary film is the story of a psychopathic cameraman – his childhood traumas, sexual crises and murderous revenge as an adult. Reviled by critics upon its initial release for its deeply unsettling subject matter, the film has since been hailed as a masterpiece.
