In this final programme, Mark Gatiss explores the explosion of American films of the late Sixties and Seventies that dragged horror kicking and screaming into the present day. With their contemporary settings and uncompromising content, films such as Night Of The Living Dead and The Texas Chain Saw Massacre remain controversial. But Mark argues that the best of these films - often regarded as being only for hardcore fans with strong stomachs - have much to offer. He gets the inside story of the films from a roster of leading horror talent. He meets director George A Romero, whose Night Of The Living Dead and Dawn Of The Dead turned zombies into A-list monsters; sits down with Tobe Hooper, the mild-mannered director of the notorious Texas Chain Saw Massacre; and joins director John Carpenter on a tour of the locations where he filmed the smash-hit Halloween, which triggered the slasher movie boom. Along the way Mark visits Bates Motel, gets mobbed by zombies and finds out what happened to Omen star David Warner's decapitated head.
