I like Copper Canyon, it's one of my favorite westerns. Admittedly the plot is somewhat convoluted and the acting, although competent, is not outstanding. I think I mainly like the cast. Hedy Lamarr is gorgeous -- as usual -- Mona Freeman was one of Hollywood's prettiest blondes, and Ray Milland is the suave, dashing hero. At the time it was made, Copper Canyon was just one of many westerns ground out during Hollywood's Golden Age, although a bit more stylish than most. But, like most Golden Age movies, it's fun to watch -- which I can't say about most movies made these days.
