Dead of Night
Dead of Night was a television anthology collection of fiction, produced by the BBC and broadcast at 1972 on BBC2. It ran for a single series. Of its own seven 50-minute episodes, just three--"The Exorcism","Return Flight", and"A Woman Sobbing"--are well all known to survive from the BBC's archives. Another programme made under Innes Lloyd by the Dead of Night production team, The Stone Tape, designed to be the episode, does survive from the archives but wasn't broadcast under the Dead of Night banner ad.
BBC Four re-broadcast"The Exorcism" on 22 December 2007.
