Double bill of made-for-TV supernatural dramas. In 'The Stone Tape' (1972), when scientists working for Ryan Electrics move into their new headquarters, a gothic mansion, they find one room unfinished. Strange noises are heard and the builders are too frightened to complete their work. When the other scientists dismiss such fears as irrational whimsy, only psychically-minded Jill (Jane Asher) senses the dark secret that lurks beneath the building. 'Ghostwatch' (1992) is a fully-scripted drama which imitated the format of a live television broadcast taking place inside a haunted house. The hoax is made all the more convincing thanks to its use of well-known TV presenters Michael Parkinson, Sarah Greene and Mike Smith.
