I vampiri di Praga

Throughout the film, Count Mora (Bela Lugosi) has an unexplained bullet wound on his temple. In the original script Mora was supposed to have had an incestuous relationship with his daughter Luna and to have committed suicide. After filming began, however, MGM deleted references to the crime (and any remaining references may have been deleted when 20 minutes of footage was removed after the film's preview). Because director Tod Browning's previous film, Freaks (1932), had been a box-office disaster, he was unable to object to any changes made by the studio.

The character of Jan (pronounced as it would be in Prague as "yan") is referred to by the English pronunciation inexplicably by one character a few times before returning to pronouncing it correctly.

There is an Italian DVD edition of this movie, distributed by DNA Srl. The movie was re-edited with the contribution of the film history scholar Riccardo Cusin. This version is also available in streaming on some platforms.
