Jesus Franco was one of the busiest men in trash cinema. In 1973 alone he did 11 films. Female Vampire is probably the most popular of that 11.
The film opens up with Lina Romay walking through the fog with nothing but her cape, belt and boots on. As she gets closer to us the camera focus's in on her finer points. Breasts, butts and bush there is plenty of. That's a promise. After all one of the many alternate titles for Female Vampire was The Bare Breasted Countess.
Then we have a bunch of scenes of Lina spreading her legs for the camera. Its nice to have an actress who isn't vagina-shy. We are treated to scenes of Lina humping the bed, hard wooden objects and even humping the bloody bath water. As I mentioned before there isn't much talking in this one. Our lead vampire is actually a mute. So she makes up for the lack of communications with straight up genital-fu.
Succubus) Taylor's character. Jack Taylor falls in love with the thousand year old vampire and from here on it plays like an nihilistic love story.
Jack Taylor's character is suicidal and doesn't want to go on living. He begs Lina Romay to take him with her to the dark side "Beyond the mist". It all finishes with a sensitive yet downbeat climax.
Female Vampire is typical Jess Franco in the sense that there is nothing typical about it. Most would despise the film but fans of artsy-fartsy Euro-trash type stuff might just enjoy it.
