context: After two years of work, in 1929, Siodmak was able to convince Nebenzal to finance his experimental film Men on Sunday (1930) based on the story of his brother Kurt. The film, which “essentially represents a series of carefree vignettes with unprofessional actors” [2], tells about two young friends having fun on a lake in the company of two girls before returning to their daily activities. The film turned out to be quite successful, it was positively received by critics and knew how to succeed with the general public. Many future Hollywood stars took part in the film: Edgar G. Ulmer was a co-director, Billy Wilder co-wrote the script, and Fred Zinnemann was the second cameraman [1] [6]. “In collaboration with these gifted people, strong directorial skills of Siodmak were inevitably formed” [3]. The popularity of this short film led to a contract with producer Erich Pommer at the UFA state film studio [2].
