Długa noc (English: The Long Night) is a Polish war film from 1967, directed by Janusz Nasfeter, based on the novel Noc by Wiesław Rogowski. The plot revolves around the dilemmas faced by the residents of a certain house in occupied Poland during World War II, where one of the inhabitants is revealed to be a collaborator with a partisan unit and a person hiding a Jew. Długa noc was one of the earliest "shelf films" – movies whose distribution was prevented by censorship during the communist regime. Created in an atmosphere of anti-Semitic sentiments, Nasfeter's film was not allowed to be shown until 1989.
