Between 1970 and 1977, a small cluster of films pushed the boundaries of ‘bad taste’ and rewrote the rules for social and sexual taboos. What made them unique was the fact that they were mostly played at midnight. Films like El Topo, Night of the Living Dead, Pink Flamingos and the legendary Rocky Horror Picture Show changed the face of cinema. This splendid documentary by Stuart Samuels tells the hidden story of these classics through interviews with directors, critics and other key players. Plus Ban the Sadist Videos, director David Gregory’s account of the Video Nasty hysteria of the early ’80s (U.K., 2005. Colour. Digital video. 52 min.)
