Vampires of Warsaw (Polish: Wampiry Warszawy) is a 1925 Polish silent crime film directed by Wiktor Biegański and starring Oktawian Kaczanowski, Halina Labedzka and Maria Balcerkiewiczówna. It was Biegański's most popular film, and displayed the influence of Soviet cinema on his work. The film is considered lost, so it is difficult to describe the plot in detail, but from what can be gathered the film appears to have been a murder mystery whodunit featuring a pair of Russian aristocrats who are determined to marry a wealthy father/daughter and murder them for their inheritance. Despite the title the film did not actually feature any vampires of the supernatural variety.
