Stone Tape
The Stone Tape is a television play directed by Peter Sasdy and starring Michael Bryant, Jane Asher, Michael Bates and Iain Cuthbertson. It was broadcast on BBC Two as a Christmas ghost story in 1972. Combining aspects of science fiction and horror, the story concerns a team of scientists who move into their new research facility, a renovated Victorian mansion that has a reputation for being haunted. The team investigate the phenomena, trying to determine if the stones of the building are acting as a recording medium for past events (the "stone tape" of the play's title). However, their investigations serve only to unleash a darker, more malevolent force.
