Don Juan is a 1926 synchronized sound American romantic adventure film directed by Alan Crosland. It is the first feature-length film to utilize the Vitaphone sound-on-disc sound system with a synchronized musical score and sound effects, though it has no spoken dialogue. The film is inspired by Lord Byron's 1821 epic poem of the same name. The screenplay was written by Bess Meredyth with intertitles by Maude Fulton and Walter Anthony.

John Barrymore was an American actor on stage, screen, and radio. A member of the Drew and Barrymore theatrical families, he initially tried to avoid the stage, and briefly attempted a career as an artist, but appeared on stage together with his father Maurice in 1900, and then his sister Ethel the following year. He began his career in 1903 and first gained attention as a stage actor in light comedy, then high drama, culminating in productions of Justice (1916), Richard III (1920), and Hamlet (1922); his portrayal of Hamlet led to him being called the "greatest living American tragedian".
