She Wore a Yellow Ribbon is a 1949 Technicolor Western film directed by John Ford and starring John Wayne. The academy award winning film was the second of Ford’s Cavalry trilogy films (the other two being Fort Apache (1948) and Rio Grande (1950)). With a budget of $1.6 million, the film was one of the most expensive Westerns made up to that time. It was a major hit for RKO. The film takes its name from “She Wore a Yellow Ribbon”, a popular US military song that is used to keep marching cadence.
