People on Sunday () is a 1930 German silent drama film directed by Robert Siodmak and Edgar G. Ulmer from a screenplay by Robert and Curt Siodmak. The film follows a group of residents of Berlin on a summer's day during the interwar period. Hailed as a work of genius, it is a pivotal film in the development of German cinema and Hollywood. The film features the talents of Eugen Schüfftan (cinematography), Billy Wilder (story) and Fred Zinnemann (cinematography assistant). Production The film is subtitled "a film without actors" and was filmed on Sundays in the summer of 1929. The actors were amateurs whose day jobs were those that they portrayed in the film—the opening titles inform the audience that these actors have all returned to their normal jobs by the time of the film's release in February 1930. They were part of a collective of young Berliners who wrote and produced the film on a shoestring. This lightly scripted, loosely observational work of New Objectivity became a surprise hit. People on Sunday is notable for its portrayal of daily life in Berlin before Adolf Hitler became Chancellor and as an early work by writer/director Billy Wilder before he moved to the United States to escape from Hitler's Germany. The film is the directorial debut of the Siodmak Brothers. The film was co-produced by Moriz Seeler, founder of the Filmstudio 1929 production company and Seymour Nebenzal, cousin to the Siodmaks, whose father Heinrich put up the money. The film began a 30-year collaborative friendship between Nebenzal and Wilder. Siodmak called it "a nice little film" and said Wilder only worked on the movie "a couple of minutes" contributing some ideas. Plot The film opens at Bahnhof Zoo train station one Saturday morning. Its opening scenes show the bustling traffic of central Berlin. The movie follows five central characters over a weekend. Wolfgang (Wolfgang von Waltershausen), a handsome young man, sees a pretty woman (Christl Ehlers) who seems to be waiting in the street for someone who has not arrived. He takes her for an ice cream, teases her about having been stood up and invites her to a picnic the following day. Erwin (Erwin Splettstößer) is doing his day job as a taxi driver. While he is fixing the car, his depot receives a phone call from his girlfriend, Annie (Annie Schreyer), who wants to know if they are going
