Ghostwatch

Sarah Greene and Craig Charles report from a reputedly haunted London home for the outside broadcast, while Michael Parkinson and Mike Smith stay in the warmth and "safety" of a BBC studio. The Early family are allegedly being harassed by the ghost 'Pipes', so named as his banging and crashing were initially attributed to bad plumbing. After a deliberately slow start the tension gradually builds, culminating in a terrifying crescendo. Although entirely fictional, the masterly combination of great scripting, intuitive direction and perfect casting made the supernatural pastiche appear frighteningly real.

An inspiration to a generation of filmmakers, and years ahead of the profusion of found footage movies that would follow, Ghostwatch is regarded as a classic of the genre and remains as relevant, as terrifying, and as inspirational today.
