David Canary's TV debut.
Filming on "Hombre" coincided with that year's Academy Awards. Co-star Martin Balsam was a Best Supporting Actor nominee for A Thousand Clowns, and not having received permission to leave the set, Balsam sneaked off to attend the ceremony. He won the Oscar.
The photo in the closing credits of the film was taken in 1886 by Camillus Fly, the famous Tombstone (AZ) photographer. The white boy in the photo is Jimmy (Santiago) McKinn, captured by the Apaches in 1885. Like the Paul Newman character in the film, McKinn was totally assimilated in the tribe and was rescued against his will when Geronimo surrendered in 1886.
