7th Heaven is a 1927 American synchronized sound romantic drama directed by Frank Borzage, and starring Janet Gaynor and Charles Farrell. While the film has no audible dialog, it was released with a synchronized musical score with sound effects using the Movietone sound system. The film is based upon the 1922 play Seventh Heaven, by Austin Strong and was adapted for the screen by Benjamin Glazer. 7th Heaven was initially released as a standard silent film in May 1927. On September 10, 1927, Fox Film Corporation re-released the film with a synchronized Movietone soundtrack with a musical score and sound effects.

A sound film is a motion picture with synchronized sound, or sound technologically coupled to image, as opposed to a silent film. The first known public exhibition of projected sound films took place in Paris in 1900, but decades passed before sound motion pictures became commercially practical. Reliable synchronization was difficult to achieve with the early sound-on-disc systems, and amplification and recording quality were also inadequate. Innovations in sound-on-film led to the first commercial screening of short motion pictures using the technology, which took place in 1923. Before sound-on-film technology became viable, soundtracks for films was commonly played live with organs or pianos.
