'Linda Blair' broke her leg while filming. She had to complete the film, including chase scenes in the sewers of Vienna, wearing a cast.
Linda Blair said in a 1999 interview that Sylvia Kristel was mentally unstable at the time because of a lot of problems in her life, so it was very difficult to work with her.
Linda Blair said this and Chained Heat (1983) almost ruined her career.
Final film of Monica Teuber.
