The Devil Horse is a 1932 American Pre-Code movie serial starring Harry Carey, Frankie Darro and Noah Beery, Sr. that was distributed by Mascot Pictures.
This is regarded as the best of the three serials Harry Carey made in the early 1930s, the other two being Last of the Mohicans and The Vanishing Legion.
Hank Canfield (Noah Beery), leader of a gang of horse thieves, attempts to steal a wild racehorse called El Diablo.
The crooks bungle the job, but they kill a Ranger named Elliott Norton (Lane Chandler) in escaping.
A young mute orphan referred to as the Wild Boy (Frankie Darro) is the only one in town who knows who the killer is, and Bob Norton attempts to communicate with the child to draw the secret out of him.
