OneEyed Jacks, a 1961 Western, is the only film directed by actor Marlon Brando. The picture was originally planned to be directed by Stanley Kubrick from a screenplay by Sam Peckinpah, but studio disputes led to their replacement by Brando and Guy Trosper. Brando portrays the lead character Rio, and Karl Malden plays his partner Dad Longworth. The supporting cast features Katy Jurado, Ben Johnson, and Slim Pickens.
After getting cornered on a high ridge, with Rios horse dead, Rio figures the Rurales will be swarming all over us inside an hour. Deciding that one partner might take the remaining pony and ride to a little jacalito down the canyon about five miles and return with fresh mounts, they shake for it, with Rio fixing the deal so his pal Dad can be the one to go.Dad gets to a corral, strapping the swag bag onto a fresh pony, but he gets second thoughts. He casts one eye towards a point on the ridge sure to be taken by the Rurales, and with the other he gazes off in the opposite direction out past a lowlying treeline towards the border and safety. One way leads to danger and a poor chance at surviving with half the booty, the other towards a virtual certainty with all of it. After a decidedly short moment of reflection, he takes the latter and leaves his friend to be taken by Rurales. Rio is arrested, and is transported to prison by way of the jacalito where he learns firsthand of Dads betrayal from the owner. ........
