Markheim (1971)

http://www.imdb.com/title/tt0933085/ "Janusz Majewski is one of Poland’s most durable and prolific filmmakers. In a career that spans half a century Majewski has directed a variety of films, with comedies and period pieces predominating. He also made LOKIS, one of Poland’s most famous horror features, and a wealth of horror-themed shorts that comprise a significant body of work in their own right. In fact, I’d argue that Majewski can be counted as the foremost director of Polish horror movies (his only real competition in this regard are his fellow countrymen Roman Polanski, Jerzy Skolimowski and Andrzej Zulawski, all of whom have made the majority of their films outside Poland)."
