The Rounders (1993)

Ben Jones (Glenn Ford) and Howdy Lewis (Henry Fonda) are cowboys who spend their days breaking horses and flirting with two sisters (Kathleen Freeman, Joan Freeman). When Ben and Howdy trade Ol' Fooler, an unbreakable horse, for corn liquor, the client returns the horse after it passes out from drinking whiskey. The cowboys grow fond of Ol' Fooler and, knowing that he is nearly impossible to ride, enter the horse in the rodeo hoping to make their fortune.
