Forget Hammer. Forget Amicus or Tigon. The 1950s and ?60s were the era of the ?X?-certificate, when the emergent British horror film was equally represented by the work of a number of independent producers who between them created some of the most memorable thrillers of the period. This was the time when madmen stalked the Circus of Horrors, Jack the Ripper rubbed shoulders with Peeping Tom, and cinemagoers were invited to walk the Corridors of Blood, enter the Theatre of Death and set foot on the Island of Terror...In X-CERT, the ?Adults Only? horror films that inspired the nightmares of a generation are examined in detail for the very first time through exclusive interviews, contemporary censorship reports and rare glimpses behind the scenes--complete with over 200 stills!
