Tudor Gates was hired to write the original script called
To Love a Vampire, following the success of
The Vampire Lovers. He says it was based on an original script he wrote for
Mario Bava about a girls school which had a serial killer. Gates liked the script and said it had "a serious love story" but then the film "all went wrong." He had to use Yvette Stugart who came from
James Carreras.
Terence Fisher was to direct but he was badly injured in a car accident. At one stage Harry Fine was going to direct but then Jimmy Sangster took over. Gates said Sangster clashed with the producers during filming over creative decisions – such as the producers insisting on a pop song being put in the film to copy the pop song from
Butch Cassidy and the Sundance Kid (1969).
Ingrid Pitt from
The Vampire Lovers was meant to star but she was busy on another film. The film was financed by EMI Films." Partially due to censorship restraints from the
British Board of Film Classification, this film and the next one,
Twins of Evil, had diminishingly overt
lesbian elements in the story than did
The Vampire Lovers. Carmilla, for example, in this film falls in love with a man.
Ingrid Pitt was offered the lead, but turned it down.
Peter Cushing was supposed to have appeared in the film, but bowed out to care for his sick wife. Cushing was replaced by Bates, who described
Lust for a Vampire as "one of the worst films ever made". Bates had earlier appeared in
Taste the Blood of Dracula with
Madeline Smith, who starred in
The Vampire Lovers. The song "Strange Love" was recorded for the film by Tracy, a teenage singer from Wembley, and released as a
7-inch single, produced by
Bob Barratt. The castle shown in the film to represent Karnstein Castle is the famous
Hochosterwitz Castle in
Austria, which was also used in the Hammer film
Twins of Evil. == Critical reception ==
