Atom Age Vampire

From Wikipedia:
Atom Age Vampire (original title Seddok, l'erede di Satana) is a 1963 black-and-white Italian horror/science fiction film directed by Anton Giulio Majano and starring Alberto Lupo.

Despite the implication of its American title, the film appears to have no direct connection with the "atom age" of the early 1960s. The title was apparently chosen to indicate to potential audiences the modern-day time period of the story.

When a singer (Susanne Loret) is horribly disfigured in a car accident, a scientist (Alberto Lupo) develops a treatment which can restore her beauty by injecting her with the glands of a murdered woman. While performing the procedure, however, he falls in love with her.
