Moonrunners is a 1975 film, starring James Mitchum, about a Southern family that runs bootleg liquor. It was reworked four years later into the popular long-running television series The Dukes of Hazzard, and as such the two productions share many similar concepts. Mitchum had co-starred with his father, Robert Mitchum, in the similar drive-in favorite Thunder Road eighteen years earlier, which also focused upon moonshine-running bootleggers using fast cars to elude federal agents. Moonrunners, a B movie, was filmed in 1973 and awaited release for over a year. Its soundtrack reflects the outlaw music boom of the 1970s during which the film was released.
The film was written and directed by Gy Waldron and is based on the life and stories of ex-moonshiner Jerry Rushing, who has a small role in the movie as a heavy at the Boar's Nest bar. It is listed in the book The Greatest Movie Car Chases of All Time.
