My review was written in March 1984 after a screening at Empire theater on Manhattan's 42nd St.
"The Black Room" is a pretentious, thoroughly unappealing horror picture whose poster and advertising promise a dark, sexy opus that does not materialize on screen. Filmed in January 1981, delayed release looks to grim box office.
The script by Norman Thaddeus Vane (who also takes a co-director credit) awkwardly meshes two separate stories: (1) Jason (Stephen Knight) is a California artist living with his beautiful model sister Bridget (Cassandra Gaviola). He suffers from a blood disease that requires replacement of his blood at least twice a week, and duo are given to ensnaring unwary young visitors in their mansion's Black Room, photographing their sex acts through a one-way mirror, and then killing them for their blood. Corpses are neatly buried in coffins in the garden.
(2): Larry (Jim Stathis) is a young married man having sexual problems with his wife Robin (Clara Perryman). Larry answers Jason's ad for a low-cost home in the Hollywood Hills and starts acting out his sexual fantasies in the Black Room with various women he picks up. Unbeknownst to him Jason and Bridget are killing his partners for their blood.
Absurd finale has both Jason and presumab;ly normal sister Bridget turning into zombies after Larry and Robin kill them, a supernatural tangent not justified by the preceding footage and guaranteed to anger a paying audience.
Film's sole highlight is a lengthy showcasint role for the exotically beautiful model-turned-actress Cassandra Gaviola (aka Gava), who later had small parts in "Conan the Barbarian", "Nighrt Shift" and "High Road to China". Casting of Stephen Knight. Who looks like an entirely different nationality, as Cassandra's brother is an error.
Technically, the film is sloppy, with frequent shots from the window side (peering into the Black Room) producing mirror images of the watcher. Picture is also an object lesson for itinerant filmmakers in how not to use the Steadicam.
