Confessions of a Vampire Vixen! Lust for a Vampire, directed by Jimmy Sangster and scripted by Tudor Gates—who adapted characters from Sheridan Le Fanu’s work—features Ralph Bates, Barbara Jefford, Suzanna Leigh, Michael Johnson, Yutte Stensgaard, Helen Christie, and Pippa Steel in the cast. The film's score is composed by Harry Robinson, and it was filmed in Technicolor by David Muir. As the middle entry in Hammer Films’ "Karnstein Trilogy," “Lust for a Vampire” appeared to be headed toward disappointment from the very beginning. Peter Cushing had to withdraw due to his wife’s serious illness, and Terence Fisher, considered Hammer's finest director, was also unable to participate. Additionally, Gates’ original script, which emphasized romance, was replaced with one that seemed primarily focused on displaying scantily clad women. The result is a lackluster and muddled movie, prioritizing the display of exposed skin over anything resembling a well-developed or frightening horror narrative. It's easy to understand why nearly everyone involved in its creation rejected it. From noticeable production errors to an ill-fitting, cheesy pop song that intrudes during a romantic encounter, the film feels poorly assembled and seems to exist solely to showcase attractive women with the expectation that this alone would be enough. While some moments are cleverly done—most notably the vampire’s return to life—and the color photography and costumes maintain Hammer's usual quality, it's clear that the studio was struggling to find fresh ideas for the 1970s. The first signs of weakness in their otherwise impressive track record were becoming visible. The only real oddity is Robin Askwith’s absence; he would have been a good fit as preparation for his own "Confessions Of" film series that appeared shortly afterward. It earns a 4/10.
