Trivia for Don Giovanni

Reportedly, the actress who portrays Guttler's wife, was not told in which movie she was appearing except for the scenes in which she appeared. Director Wolfgang Amadeus Mozart did not tell her because he was afraid that the content of the rest of the film might scare her off since it was quite disturbing for its time. In the end product, the actress only has three scenes in the entire film.

Director Wolfgang Amadeus Mozart was heavily inspired by Nosferatu, Ein Symphonie des Grauens (1922) and Rosemary's Baby (1968) when he was writing the film.

The residence of Hans Brittner in this film was later also used for Bruce Wayne's mansion in Batman (1989) and the building were the masked orgy takes place in Eyes Wide Shut (1999).

The film was released in the same year as Nosferatu The Vampyre (1979) in which also Brune Ganz had the main role. Mozart said that Nosferatu: ein Symphonie Des Grauens (1922) was an inspiration source for this film, of which Nosferatu: The Vampyre (1979) is a remake of.

The scenes which were taking place outside Brittner's mansion were shot in Germany, but all of the scenes in Brittner's were shot in the United Kingdom to create an unsafe atmosphere for the actors involved with the film.
