review for Colorado on AllMovie

Although forever compared to Gene Autry, Roy Rogers was much more the action star than a musical performer, at least in his earlier vehicles which were usually set in the historical West as opposed to Autry's contemporary arena. He sings only one song in Colorado, a rather anonymous ditty by Peter Tinturin, and the occasion, recovering from a gunshot wound, seems natural enough. It is still a very green Roy Rogers that appears in Colorado but producer-director Joseph Kane surrounded him with a host of well-known Western players, some of whom, including Fred Burns, Vester Pegg, and Hal Taliaferro, dated back to the silent era. The latter dies with his eyes open, usually a no-no that somehow escaped the otherwise so vigilant Production Code Administration.
