The Blood Beast Terror (1968)
Starring: Peter Cushing, Robert Flemyng and Wanda Ventham
Director: Vernon Sewell
Rating: Three of Ten Stars
A blood-sucking creature is on the loose, and Inspector Quennel (Cushing) is hot on its trail. All the clues point to the household of harmless entomologist Dr. Mallenger (Flemyng). Can his wanton, promiscious daughter (Ventham) be a literal man-eater?
Peter Cushing reportedly described this movie as the worst one he was ever in. While it isn't all that good--it's slow-moving, it's requirements for special effects to turn a buxom babe into a giant blood-sucking moth are beyond the meager budget it was produced with, and the ending is one of the most abrupt and badly motivated among the many abrupt and badly motivated endings of British monster movies from the 1950s and 1960--but it isn't anywhere near as bad as "Scream and Scream Again," so I can only assume that either Cushing had a better time making the latter film or he hadn't made it yet when he talked down "Blood Beast Terror".
While it's certainly true that this is one of those very rare occasions where Cushing doesn't seem to be giving the role his all--this is the only time I remember feeling like he "phoned in" his performance--he still brings more life to the scenes he's in than is found virtually anywhere else in the film. In fact, aside from Cushing, the only interesting thing in the picture is Wanda Ventham (or, more specifically, Wanda Ventham's cleavage).
This is a film you can safely skip until you've seen every other Peter Cushing movie there is. And, yes, that includes "Top Secret!"
