When Four Do the Same () 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' character's 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.
The film was shot at the Tempelhof Studios in Berlin. It premièred in Berlin on 16 November 1917 at the Union-Theatre am Nollendorfplatz and at the UT Kufürstendamm (Filmbühne Wien).
