When Four Do the Same (German:Wenn vier Dasselbe tun) is a 1917 German silent comedy drama film directed by Ernst Lubitsch and starring Ossi Oswalda, Emil Jannings and Margarete Kupfer. Lubitsch himself plays a book shop employee who falls in love with Jannings' daughter. The film was a key transitional work in Lubitsch's career, as he began to produce films with greater depth than his early light comedies.
