Columbia Pictures originally intended this film as a direct sequel to Dracula (1931), also starring Bela Lugosi, but when Universal threatened a plagiarism suit, Columbia went ahead and made the film anyway but changed the names of the characters to avoid any connection with "Dracula". It also held back its release for two months so as not to compete with Lon Chaney Jr.'s Il figlio di Dracula (1943).

Bela Lugosi was paid $3,500 for his four weeks of work.

The original idea for this film was created by German born director Kurt Neumann. However, it was directed by prolific "B" film specialist Lew Landers, who would have another half-dozen films in release that same year.

According to "The Films of Bela Lugosi", Columbia grossed close to $500,000 from this film on an investment of $75,000.

Bela Lugosi filmed this Columbia feature August-September 1943, prior to his final two Monogram films. This was also the last time he would receive top billing for a major Hollywood studio.
