Strong Boy is a 1929 American Synchronized sound comedy film directed by John Ford. While the film has no audible dialog, it was released with a synchronized musical score with sound effects using the sound-on-film Movietone process. The film, which was Ford's last silent film, is now considered to be lost. A trailer for the film was discovered in the New Zealand Film Archive in 2010 and subsequently preserved by the Academy Film Archive the same year.
