Sky has created a new video advert featuring a mock haunted house to promote its upcoming three-part drama 'The Enfield Haunting'.
The Sky Living series, which stars Timothy Spall and Matthew MacFadyen, explores the evidence of the famous Enfield poltergeist, which captured the imagination of the nation in the late 1970s.
One of the residents in an Enfield council house, 11-year-old Janet Hodgson, became convinced she was possessed by a former resident of the Green Street property.
The haunting puzzled policemen, psychics and even experts in the occult, gaining national press coverage in the process.
To promote the new TV dramatisation of the story, Sky Living created a three-minute clip showing the impact of a fake haunting on a number of estate agents.
They were invited to value an Enfield property - fitted with secret cameras - which was reported to have been vacated by a recently deceased man.
The house was booby-trapped to give the impression there was a ghostly presence, with a number of unexplainable events taking place.
The Sky Living ad shows the reaction of several estate agents to taps turning on, cupboards opening by themselves and items of furniture moving around the room.
'The Enfield Haunting', which Sky says is 'coming soon' to TV secreens, is based on Guy Lyon Playfair's book 'This House is Haunted'.
It draws on extensive documentation, recordings and witness statements relating to the most documented account of ghostly activity in UK history.
