Ghostwatch is a British reality– horror/ mockumentary television film, first broadcast on BBC1 on Halloween night, 1992. Written by Stephen Volk, and directed by Lesley Manning, the drama was produced for the BBC anthology series Screen One by Richard Broke, Ruth Baumgarten and Derek Nelson.
Despite having been recorded weeks in advance, the narrative was presented as live television. During and following its first and only UK television broadcast, the show attracted a considerable furore, resulting in an estimated 30,000 calls to the BBC switchboard in a single hour.
Ghostwatch has never been repeated on UK television. It has been repeated internationally, on stations such as the Canadian digital channel Scream for Halloween 2004, and the Belgian channel Canvas in 2008. There have been two UK home video releases - in 2002, the British Film Institute released a 10th Anniversary edition on VHS and DVD, and in 2011, 101 Films issued a DVD release.
A retrospective documentary, Ghostwatch: Behind the Curtains, based on the film's lasting impact, was released on DVD in 2013 (having been in production between 2007-2012), featuring interviews with many of the original cast and crew.
