The Big Parade is a 1925 American silent war drama film directed by King Vidor, starring John Gilbert, Renée Adorée, Hobart Bosworth, Tom O'Brien, and Karl Dane. Written by World War I veteran Laurence Stallings, the film is about an idle rich boy who joins the U.S. Army's Rainbow Division, is sent to France to fight in World War I, becomes a friend of two working-class men, experiences the horrors of trench warfare, and finds love with a French girl. A sound version of the film was released in 1930. While the sound version of the film has no audible dialog, it featured a synchronized musical score with sound effects using both the sound-on-disc and sound-on-film process.
