Good old fashioned Western, the plot however is very similar to the Jimmy Cagney classic "The Roaring 20's" re-fashioned to a Western setting and with a sanitised ending, McCrea as the Cagney character survives and Scott as the Bogart character is killed after changing sides back to the law and Order camp. Worth watching as a good example of Hollywood in its pre message era when a Western was for entertainment. The production values were good with great Technicolour and a strong cast. McCrea was always good in his Westerns having played both comedy and drama in his earlier years and Zachary Scott was a very under-rated actor, good in any movie he was in.
