Dillinger is a 1973 American gangster film about the life and criminal exploits of notorious bank robber John Dillinger. It stars Warren Oates as Dillinger, Ben Johnson as his pursuer, FBI Agent Melvin Purvis, and Cloris Leachman as the "Lady in Red" who made it possible for Purvis to kill Dillinger. It also features the first film performance by the singer Michelle Phillips as Dillinger's moll Billie Frechette. The film, narrated by Purvis, chronicles the last few years of Dillinger's life (depicted as a matter of months) as the FBI and law enforcement closed in. The setting is Depression era America, from 1933 to 1934, with largely unromanticized depictions of the principal characters. It was written and directed by John Milius for Samuel Z. Arkoff's American International Pictures.
Retired FBI Agent Clarence Hurt, one of the agents involved in the final shootout with Dillinger, was the film's technical advisor. The film includes documentary imagery and film footage from the era. It includes a verbal renouncing of gangster films written by FBI chief J. Edgar Hoover: he was scheduled to read it for the film, but died before it started production. Hoover's text is read at the film's close by voice actor Paul Frees.
