Extreme Ghost Stories is a British supernatural documentary television series produced by ITV Granada, consisting of four one-hour episodes. In 2005, ITV Granada appealed for those whose lives had been affected by ghostly experiences to contact the station regarding production of a paranormal series. The series was broadcast by ITV in 2006, and was later shown on American cable channel WE tv in September 2007. The series featured drama reconstructions of ghostly encounters of some well-known haunted locations as well as individual cases not known to paranormal enthusiasts. Featured in episode three were interviews with resident Most Haunted Live! historian and Most Haunted: Midsummer Murders presenter Lesley Smith. The series was narrated by veteran Rob Brown. A recurring supernatural entity in the series is the black mass, an appalling dark form with a vaguely humanoid stance, which witnesses unanimously feel represents pure evil.
