Hoppy goes undercover as an outlaw (which permits him, for once, to drink and be mean to children) to track down a bunch of outlaws operating along the border. Loco, the head bad guy, deflects suspicion from himself by pretending to be a moron.
Acting
Boyd's hilariously unconvincing 'outlaw' persona is accidental comedy gold.
Writing
Loco's 'pretend moron' defense—surprisingly clever for 1937 B-picture plotting.
Practical Effects
Genuine stunt riders and dust—you feel every hoofbeat.

Director
Nate Watt
Trivia, insights & behind the scenes
William Boyd made 66 Hopalong Cassidy films; this rare 'mean Hoppy' role was his vacation from virtue.
Boyd's Hopalong became so wholesome that his 1950s TV edit removed even this mild 'drinking outlaw' phase.
