The Rounders (1965)

Acclaimed western screenwriter Burt Kennedy's third film as both writer and director is the cheeky western The Rounders (1965) starring Hollywood legends Glenn Ford and Henry Fonda as Ben and Howdy, two aging lothario cowboys always looking to make a quick buck. When they are given a horse that can't be broken as payment in lieu of money, they decide to run a con at the local rodeo, fooling unsuspecting bronco busters into trying to tame this wild horse. Their con goes off without a hitch, for a while, putting money in their pockets and leading the two to compete for the affections of some local lasses. In the film's sexiest scene, a pair of comely young ladies played by Hope Holiday and Sue Ann Langdon bare their buns while attempting to cover themselves! Sadly, Sue Ann used a body double, but that's one hundred percent Hope Holiday's heinie you're looking at!
