Vampires of Warsaw

Vampires of Warsaw 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's difficult to describe the plot in detail, but the film appears to have been a murder mystery whodunit and did not actually feature any vampires of the supernatural variety.
