Well-directed by William Witney and eschewing long musical interludes in favor of action, Grand Canyon Trail remains less of a Roy Rogers tour de force than a vehicle for actress/singer Jane Frazee, a fine comedienne and Roy's best leading lady next to Dale Evans. This is the last of five Westerns for the team and director William Witney allows Frazee to dominate much of the goings-on, which she manages with her tongue firmly planted in cheek. She is much more active than the usual prairie heroine, and it is Jane who gets to dispatch villainous Robert Livingston with a handy rock, thus saving Roy's life. Foy Willing & the Riders of the Purple Sage make their first appearance in a Rogers Western and Grand Canyon Trail also features a rather subdued James Finlayson, of Laurel and Hardy fame, as the sheriff.
