Sunrise: A Song of Two Humans is a 1927 American synchronized sound romantic drama directed by German director F. W. Murnau and starring George O'Brien, Janet Gaynor, and Margaret Livingston. The film's plot follows a married farmer (O'Brien) who falls for a woman vacationing from the city (Livingston), who tries to convince him to murder his wife (Gaynor) in order to be with her. While the film has no audible dialogue, it was released with a synchronized musical score with sound effects using the Movietone sound-on-film process. The story was adapted by Carl Mayer from the short story "The Excursion to Tilsit", from the 1917 collection with the same title by Hermann Sudermann.
