I give this movie an E for effort - Mitchum plays an American who had escaped to Mexico in his youth after a violent episode and has grown up working for the local bandits controlling that part of the country. When sent to a US border town to negotiate a weapons deal, he breaks his leg and spends enough time in he US to realize he could make a life for himself with a brighter future - of course things go wrong. Based on a novel by Tom Lea, a forgotten writer of westerns, and staring along with Robert Mitchum in the romantic triangle is Gary Merrill as the local cavalry boss and Julie London as his unhappy wife. What makes it all interesting is the fact that the movie never quite "jells"- Mitchum tries his best against a cast of grade B actors and his performance mostly works. The worst performance is from Julie London who not only is dressed incongruously but looks and acts like a robot. The scenery is spectacular and is the winner in this movie. Add the use of over the top music, and this movie presages the Spaghetti Western.
