Two Thoroughbreds is a 1939 American drama film directed by Jack Hively, written by Joseph Fields and Jerome Cady, and starring Jimmy Lydon, Joan Leslie, Arthur Hohl, J.M.
[1][2][3] When thieves steal Larkspur, a prize thoroughbred brood mare, from the Conway ranch, her foal runs after her and is found by David Carey, an orphan who lives with his heartless aunt Hildegarde and uncle Thad.
The lonely David befriends the colt, whom he names Sunset, and convinces his brutal uncle to let him keep the animal, arguing that they can reap a reward from selling the horse.
While visiting the Conway ranch in search of advice about raising his horse, David is befriended by Jack Lenihan, the stablemaster, who offers the boy a job in exchange for special food for his colt.
Touched by David's confession, Conway convinces the skeptical vet, Dr. Purdy, to use an experimental cast on the horse's broken leg, and after a shaky start, Sunset makes a miraculous recovery.
