James Caan was 27 when cast as knife-throwing gambler Mississippi in Howard Hawks’ first remake of Rio Bravo, El Dorado.

Co-starring opposite John Wayne and Robert Mitchum in the 1966 Western was a massive deal, and over the years, he’s shared some shocking stories of the shenanigans and, at times, fiery altercations he had with Duke.

Acting opposite Wayne meant that Caan, who was the same height as Tom Cruise at 5ft 7in, had to wear three-inch lifts next to the towering Western legend.

The pair became close on set but not before Duke had his fun pranking the rising star through intimidation.

Caan, who died in 2022 and would have been 85 this week, said in interviews how Wayne would call him “kid” and say things like “You’re doing a lot of smiling Jiminy Cricket” because of his hat.

During their breaks, they would sometimes play chess and one time the young actor accused Duke of cheating, which sparked a violent argument between them that Robert Mitchum had to cool down by intervening.

Speaking on The Tonight Show in 1997, Caan said of Wayne: “If he could intimidate you, he’d stay on you forever until you just crumbled. He’d try you. So this one night I remember I was between he and Robert Mitchum and Howard Hawks was about 72 at the time and we’re outside in this big old Western town.”

The Godfather star shared how Duke would approach him and tell him to turn around in a shot, take a step and “Give me that look that you me.” The young actor would do as Duke told him, but then director Howard Hawks would yell “Cut!” and tell him not to take the step.

The Western star then told him again to take half a step and this went back and forth until the Mississippi actor blew up. Caan admitted: “I was gonna hit him!” However, Mitchum ran up and broke up the confrontation just like with the chess game.

Caan declared: “He knew what he was doing, he was having a good time at my expense!” From then on they became good pals who would go out of their way to try and screw each other’s scenes up. The Mississippi actor remembered putting off Wayne by mouthing “You snake!” at Duke, which made him laugh.

That was until one day the 27-year-old couldn’t get into his dressing room as it was locked, so he asked for the key. He revealed: “Garbage just came out! He piled it with garbage, he was like a 12-year-old kid Duke.”
