Paulina Mlynarska, who played the main role, was 14 years old when the film was being shot; she claims that she was drugged with sedatives and alcohol in order to record the erotic scenes with her participation. She blames Andrzej Wajda for this.
A love scene between Paulina Mlynarska and Piotr Wawrzynczak has been removed from the film. The couple's nude run was also cut from the film.
Based on the novel of the same title by Tadeusz Konwicki. He is also in the cast, playing the Stranger.
