Darby's Rangers (released in the UK as The Young Invaders) is a 1958 war film directed by William Wellman and starring James Garner as William Orlando Darby, who organizes and leads the first units of United States Army Rangers during World War II. The movie was shot by Warner Brothers Studios in black and white, to match wartime stock footage included in the production. The film was based on the 1945 book Darby's Rangers: An Illustrated Portrayal of the Original Rangers, by Major James J. Altieri, himself a veteran of Darby's force. The supporting cast features Jack Warden and Stuart Whitman.
