The idea for Roman Polanski's short movie (his diploma piece from Lodz Szkola Filmowa and his first one in color) was taken from a short story "Klozet Babcia", written by Leszek Szymanski and published weekly "Kierunki" in Warsaw, Poland.
Barbara Lass (the actress who plays the young woman) and Roman Polanski got married the same year this movie was released. They divorced in 1962.
