Not quite as memorable as his previous Riders in the Sky, Gene Autry's Sons of New Mexico is still well up to the star's standard. This time, Gene tries to reform Randy Pryor, a would-be juvenile delinquent, played by Autry-protégé Dick Jones (who later starred in the Autry-produced TV series Range Rider and Buffalo Bill Jr).

The kid chafes at the school's regimen and escapes, heading back to his criminal mentor Pat Feeney (Robert Armstrong).

Produced by Jack Schwartz for low-budget company Screen Guild, this mild Western starring the veteran Richard Arlen was apparently the first entry in a proposed series. Arlen played the title role, here assigned by the army to quell an Indian attack on the powerless settlers. The Indians are accusing Tom Russell (John Dexter) of murdering a member of the tribe, an act, as Buffalo Bill discovers, actually committed by a gang of outlaws hired by investment company owner J.B. Jordon (Frank O'Connor). Buffalo Bill Rides Again was soundly defeated by a low budget and slipshod direction by the veteran Bernard B. Ray. Popular B-Western villain Ted Adams disappeared mysteriously halfway through the film, only to be replaced by Edmund Cobb. Jennifer Holt, the daughter of Arlen contemporary Jack Holt and by far the busiest B-Western heroine of the 1940s, had little to do other than letting herself be kidnapped by evil Gil Patric.
