The Appaloosa (also known as Southwest to Sonora) is a 1966 American Western film starring Marlon Brando, Anjanette Comer, and John Saxon, who was nominated for a Golden Globe for Best Supporting Actor for his portrayal of a Mexican bandit.

Based on the 1963 book by Robert MacLeod,[2] the title character is a beautiful horse (a breed, the Appaloosa) belonging to Matt Fletcher (Marlon Brando), a Mexican-American buffalo hunter who returns home, only to have his beloved horse stolen by a powerful bandit, Chuy Medina (John Saxon) with the help of the bandit's girlfriend, Trini (Anjanette Comer) in the border town of Ojo Prieto.

A later foray into Medina's camp results in a brutal arm wrestling match in a bar between Fletcher and the bandido.

Fletcher, realizing that Trini means more to him than the horse, sends out the Appaloosa to draw Chuy's fire.

As the bandit prepares to aim for the horse, sunlight glints on his gun barrel, revealing his position.
