Paris Blues (1961) is an American feature film made on location in Paris, starring Sidney Poitier as expatriate jazz musician Eddie Cook, and Paul Newman as trombone-playing Ram Bowen. The two men romance two vacationing American tourists, Connie Lampson (Diahann Carroll) and Lillian Corning (Joanne Woodward) respectively. The film also deals with American racism of the time contrasted with Paris's kinder treatment of African Americans. The film was based on the 1957 novel of the same name by Harold Flender.
The film also features trumpeter Louis Armstrong (as Wild Man Moore) and jazz pianist Aaron Bridgers; both play music within the film. It was produced by Sam Shaw, directed by Martin Ritt from a screenplay by Walter Bernstein, and with cinematography by Christian Matras. Paris Blues was released in the U.S. on September 27, 1961.
