One of the previous posters mentioned a Gable-Tracy movie. That would've been Boomtown. About a couple of wildcatters who form a partnership to find oil. It follows them as they make fortunes, lose them and romance Claudette Colbert and Hedy(not Hedley) Lamar. Very good movie. A few other Gable movies with a western theme are Honky Tonk with Lana Turner, Lone Star with Broderick Crawford and, The Painted Desert with Bill Boyd.
