The Kid from Texas (1939 film)

[1] Margo Thomas, a lady of New York high society, travels to Texas with her brother to buy a new polo pony.

Trying to learn her favorite sport, William leaves the estate in shame after being thrown from a horse during a polo match.

He still loves the game, so he and Snifty begin a series of Wild West polo matches in the city, "cowboys against Indians," that become popular.

Margo's brother's team ends up playing his, and after impressing her with his skill, William deliberately loses the match, just to please her.

Australian sports star Snowy Baker trained actor Dennis O'Keefe to play polo for the film.
