The Guns of Loos is a 1928 British sound war film directed by Sinclair Hill and starring Henry Victor, Madeleine Carroll, and Bobby Howes. The film was given a limited release as a silent film before being converted into a sound film late in 1928. While the sound version of the film has no audible dialog, it was released with a synchronized musical score with sound effects using both the sound-on-disc and sound-on-film process. Like the majority of films from the early sound era, this film was made available in a silent version for theatres that had not yet converted to sound.
