When Four Do the Same

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.

It premièred in Berlin on 16 November 1917 at the Union-Theatre am Nollendorfplatz and at the UT Kufürstendamm (Filmbühne Wien).
