Ghostwatch is a British mockumentary supernatural horror 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 furor, resulting in an estimated 1,000,000 phone call enquiries to the BBC switchboard on the night of broadcast, comprising a mixture of complaints and praise for the programme's unique presentation. This outrage is often compared to Orson Welles' 1938 The War of the Worlds radio broadcast and the 1994 Without Warning television film, both of which also allegedly caused nationwide panic in the United States.
