House of Whipcord (1974)
House of Whipcord is a 1974 horror exploitation film directed by Pete Walker. It was his first collaboration with former Time Out critic and screenwriter David McGillivray, who went on to write a further three films for him. It also marked the horror film debut of distinguished character actress Sheila Keith, who went on to star in a further four films for Walker. "House of Whipcord" begins with the ironic credit: "This film is dedicated to those who are disturbed by today's lax moral codes and who eagerly await the return of corporal and capital punishment".
