Bruce Dern struggled to seek out appearing jobs after co-starring reverse John Wayne in The Cowboys.

His troubles started even earlier than filming on the 1972 Western started.

Duke had just given an incredibly controversial Playboy interview sharing his views on civil rights and the remedy of Native Americans.

In truth, Laura Dern remembers on the time a few of her buddies’ mother and father ended up cancelling play dates along with her due to her father’s involvement within the film.

But what occurred on set affected his profession much more.

Speaking beforehand with Cowboys and Indians, Dern was requested if he was intimated by Wayne on set in any respect. He replied: “I might have been. But right at the start, he says to me, ‘I want you to do us a favour.’ He was including himself, [director] Mark Rydell, and the scriptwriters. He said, ‘From now on, consider me to be somebody you can publicly kick the s*** out of 24 hours a day on the set. Because I want these little kids [playing the cowboys of the title] to be absolutely terrified of you.’

“He gave me carte blanche to just treat him like a turd. So I was on him, talking back to him and stuff, for the few days I was there. And he would do things like call out: ‘Hey, Mr Dern, would you get over here?’ I thought, Hey, John Wayne gives you a ‘mister’ status. My first day, he’s calling me mister. How about that? That’s pretty cool.”

However, the satisfaction of this perk can be short-lived. Half a century later, Dern has stated he nonetheless receives hate mail after his character Asa Watts killed Wayne’s Wil Andersen in The Cowboys. But he knew it was coming and so did Duke.

Asked if he nonetheless runs into followers who're upset about it, the actor stated: “No question. But I knew that would happen. I knew on the day when I had to shoot him, when we did that scene, that he had never even had a bullet squib put on him before in his career. You know, he got shot in Sands of Iwo Jima. I think he got killed by some sniper. But this was the first time he actually had a squib put on him, where it was going to be close to his skin and everything else. [Laughs.] I remember he leaned into me at about 8:15 am that morning, reeking of Wild Turkey 101.”

Dern continued: “[Wayne] said, ‘Is it gonna hurt?’ And I said, ‘Duke, they’re gonna blow your [bleeping] chest off. Get a metal protector to put underneath those squibs so the squibs aren’t next to your skin.’ ‘Oh, how do I do that?’ I said, ‘How do you do it? Order the effects man, like you order everybody else, to go ahead and do that for you.’

“Then, after he got all fitted up, he told me: ‘Oh, I want to remind you of one thing. When this picture comes out, and audiences see you kill me — they’re gonna hate you for this.’ I said, ‘Maybe. But at [UC] Berkeley, I’ll be a [bleeping] hero!’ He laughed at that. And then put his arm around my neck, turned me to the crew — there’s about 90 people there where we shot the thing, getting ready to do the scene — and he said, ‘That’s why this [bleep] is in my film. Because he understands that bad guys can be funny. If they weren’t, why would we be talking about them 150 years later?’”
