Atom Age Vampire (1963)

Atom Age Vampire is a 1963 black-and-white Italian horror-science fiction film that was directed by Anton Giulio Majano and starred Alberto Lupo.
The original title was Seddok, l'erede di Satana, mainly because it was made in Italy.
And despite the title, there is no real vampire in the movie.
Well the murders in the movie do resemble a vampire killing...well you need to see it to get what I'm talking about.

Anyway, when stripper Jeannette Morineau (Suzanne Loret) is horribly disfigured in a car accident, a scientist, Prof. Alberto Levin (Alberto Lupo) develops a treatment which can restore her beauty by injecting her with a special serum.
While performing the procedure, he falls in love with her.
As the treatment begins to fail, he determines to save her appearance, regardless of how many women he must kill for her sake.
