Locations and Dates

FILMING LOCATIONS & RELEASE DATES
Lair was filmed at Elstree Studios in Hertfordshire, Gaddesden Place, overlooking the Gade Valley, and Knebworth House, also Herfordshire, UK.
Gaddesden Place The supposed residence of Lady Sylvia Marsh. Ken Russell had previously used this location for his ridiculously pretentious Gothic. While Lair succeeds by infusing humour and kitsch with the unlikely story, Gothic unfortunately only comes across ponderous, laboured rubbish and no amount of sexual nightmares and winking breasts can rescue it. He again used this location for his explicit 1992 television version of Lady Chatterley's Lover.
	Knebworth House The grounds host the famous rock festival, so I suppose it's only fitting that Lord James D'Ampton places speakers on the roof. This is the stately home for the family of Victorian novelist Edward Bulwer-Lytton ('Pelham', 'Paul Clifford', 'Eugene Aram', 'The Last Days of Pompeii', 'Rienzi', 'Zanoni', 'Last of the Barons', 'The Caxtons' etc.), who converted the architecture of the house into a Gothic fantasy palace. Quite an appropriate choice, really.
Release Dates According to the IMDb (and I have no reason to doubt them) the film was first released in the US on 21st October 1988, in Portugal in February 1989 and France on 15th March 1990. The video was relased in the UK (PAL format) on 24th April 1991.
