Warner Archive has announced another wagonload of Westerns, and there are a few good 50s ones in there.
Cole Younger, Gunfighter (1958) is an Allied Artists CinemaScope concoction with Frank Lovejoy as the famous outlaw. The always capable R.G. Springsteen directed.
Fort Vengeance (1953) is a Cinecolor Canadian Mountie picture from Lesley Selander, starring James Craig and Rita Moreno.
Hiawatha (1953) is an adaptation of the Longfellow poem from Kurt Neumann. John Knight pointed out that this was the last film to bear the Monogram logo.
The Boy From Oklahoma (1954) stars Will Rogers, Jr., Lon Chaney, Wallace Ford and Merv Griffin. Michael Curtiz directed. It was the basis of the Sugarfoot TV series.
The Gun Hawk (1963) isn’t a 50s Western but with Rory Calhoun and Rod Cameron in it, it might as well be. A quick glance at the still below will tell you where some of it was filmed.
