The Dirty Dozen is a 1967 war film directed by Robert Aldrich, released by MGM, and starring Lee Marvin. The picture was filmed in England and features an ensemble supporting cast including Ernest Borgnine, Charles Bronson, Jim Brown, John Cassavetes, Telly Savalas and Robert Webber. The film is based on E. M. Nathanson's novel of the same name that was possibly inspired by a real life group called the "Filthy Thirteen". In 2001, the American Film Institute placed the film number 65 on their 100 Years... 100 Thrills list. In England, in the spring of 1944, Allied forces are preparing for the D-Day invasion. Among them are Major John Reisman (Lee Marvin), an OSS officer; his commander, Regular Army Major General Sam Worden (Ernest Borgnine); and his former commander Colonel Everett Dasher Breed (Robert Ryan). Early in the film the personalities of the three men are shown to clash and the characters of the individualistic Reisman and the domineering Breed are established. Reisman is aided by his friend, the mild-mannered Major Max Armbruster (George Kennedy). Major Reisman is assigned an unusual and top-secret pre-invasion mission: gather a small band of the Army's worst ex-soldier convicts (some awaiting execution) and turn them into commandos to be sent on a suicide mission, an airborne infiltration and assault on a chateau near Rennes in Brittany.
