This is an underrated western with a great moral lesson about both racism and judging too quickly from appearances. The townspeople led by Pat Hingle in this northern leaning western town hire Yul Brynner to gun down George Segal who has returned from the Civil War after fighting for the Confederacy. George Segal has come back to claim his land and his woman, each of which has been taken by another.
AS the movie progresses it's slowly revealed that the Union leaning town is not what it seems to be. Pat Hingle plays a politician very common for 30 years after the Civil War, adept at what they called "waving the bloody shirt." Just demagogue away at who did what and where during the war and ignore the current issues both social and economic.
During the course of The Magnificent Seven, Yul Brynner's Chris Adams is referred to as a Cajun. Here he's given a proper Cajun name of Jules D'Estaing and when his secret is revealed, a whole lot of people in that town have to confront their own prejudices.
Makes for worthwhile viewing.
