Notorious 1975 exploitation movie directed by Richard Fleischer and starring James Mason, Susan George and Ken Norton as the titualar character. Plot outline from The Internet Movie Database:

A slave owner in the 1840s trains his slaves to be bare-knuckle fighting champions, unaware that his daughter is having an affair with his top fighter.

This statement says nothing of the various horrible episodes of antebellum life portrayed throughout the film, the most revolting one reducing a great actor (Mason) to propping his feet on a young crouching slave, because it would "cure his rheumatism". Based on the novel by Kyle Onstott and the play by Jack Kirkland.

Man*din"gos (?), n. pl.; sing. Mandingo. Ethnol.

An extensive and powerful tribe of West African negroes.
