Ossessione carnale

The house is Oakley Court, used for exteriors in several Hammer films, and for The Rocky Horror Picture Show (1975). It was later turned into a luxury hotel.

In the opening sequence, before the audience knows any character names, actor Murray Brown is seen murdering 2 naked women, actresses Marianne Morris and Anulka, in bed together. The real estate agent in the final sequence refers to this as having occurred 40 years before the present action of the film. but vampires cannot be killed by bullets, and Brown doesn't appear to have aged at all in that time.

The original UK cinema version was heavily cut by around 3 minutes by the BBFC and the 1989 video was pre-cut but lost a further 26 secs with edits to a lesbian shower scene, sexual thrusting during the sex scene between Fran & John, the stabbing of Rupert, blood being licked from John's arm wound, closeups of Fran & Miriam's naked bloody bodies in the pre-credit scene, and the stripping and stabbing of Harriet in the cellar. The cuts were fully waived for the 2003 UK Anchor Bay DVD.
