Rawhide (1938)

Synopsis
Singing cowboy Smith Ballew is the nominal star of Rawhide, but the audience only had eyes for Ballew's co-star: baseball-great Lou Gehrig, in his one-and-only screen appearance. Gehrig plays "himself"-that is, he's a rancher named Lou Gehrig. Pressured by crooks to give up his spread, Gehrig, his sister (Evelyn Knapp) and cowboy-lawyer Ballew inspire the neighboring ranchers to form a united front. During a climactic fist-fight in a pool hall, Gehrig utilizes his pitching skills to subdue the villains. A fan of B westerns in real life, Gehrig does his best to fit into the proceedings of Rawhide; his acting is strictly from hunger, but he does possess an imposing physique and an eagerness to the please the filmgoers. ~ Hal Erickson, All Movie Guide
