Peeping Tom - Michael Powell's controversial and disturbing masterpiece about a focus puller whose relationship with his manipulative psychologist of a father leads him to obsessive voyeurism and murder, is now recognised as one of the supreme achievements of British horror cinema. In accurately linking the relationship between voyeurism and cinema it looked forward with intelligence to the franker treatment of sexual pathology to come. At the time though, it proved too much for critics to stomach and their hostility severely dented Powell's reputation.
