2. Home Counties Horror

Mark uncovers stories behind the films of his favourite period - the 1950s and 60s - which fired his lifelong enthusiasm for horror. These mainly British pictures were dominated by the legendary Hammer Films, who rewrote the horror rulebook with a revolutionary infusion of sex and full-colour gore - all shot in the English Home Counties.

3. The American Scream

Mark explores the explosion of American films of the late 1960s and 70s which dragged horror kicking and screaming into the present day. With their contemporary settings and uncompromising content, films like Night of the Living Dead and The Texas Chain Saw Massacre remain controversial. But Mark argues that these films - often regarded as only being for hardcore fans with strong stomachs - have much to offer. Made by pioneering independent filmmakers, they reflected the social upheavals of American society and brought fresh energy and imagination to the genre. Mark gets the inside story from a roster of leading horror directors, including George A Romero, whose Night of the Living Dead and Dawn of the Dead turned zombies into A-list monsters; Tobe Hooper, director of the notorious Texas Chain Saw Massacre; and John Carpenter, whose smash hit Halloween triggered the slasher movie boom. Mark also celebrates the other great horror trend of the era - a string of satanically-themed Hollywood blockbusters, including Rosemary's Baby, The Exorcist and The Omen. Along the way Mark visits the Bates Motel, gets mobbed by zombies and finds out what happened to Omen star David Warner's decapitated head.
