Helen Mirren Says She and Harrison Ford ‘Shoot the S— Off-Set’ While Filming 1923 (Exclusive)

Vibes are high on set when Harrison Ford and Helen Mirren are around.

The actors, who star as couple Jacob and Cara Dutton in the Yellowstone prequel series 1923, tell PEOPLE that they always had a “good time” — and reveal what their dynamic is like when the cameras aren’t rolling. “We would sit around together and shoot the s— off-set,” Mirren, 79. says.

“Harrison is not like an, ‘I’m going to my trailer’ person. I don’t think I ever knew him [or] remember him going ever to his trailer,” she says. “We hang around on the set and we do our thing.”

“We had a good time,” Ford, 82, agrees. “A good time hanging out together as well as working together.”

Calling her costar “such a bloke,” Mirren describes the aura that Ford seems to have around him — and how it attracts everyone else on set with them.

“He’s what in England we call a bloke. He is a guy, and because he’s a bloke, all the other blokes absolutely love him, and quite rightfully,” she says. “And he’s always so lovely to all the other actors.”

She continues, “The other guys just gather around Harrison because they just want to be in his company, I think. And I tag along.”

As for Ford’s take, he says, “If I’m a bloke, she’s what we used to call a broad — and there’s no disparagement in calling a Dame a broad.”

“It means that she’s a woman that has the bandwidth to hang with men — not just to be a lady with them, but to actually hang with them,” he says of Mirren. “She’s a real cool lady.”

In season 2 of 1923, Ford and Mirren’s characters face challenge after challenge as they fight to defend their Montana ranch from a deadly winter and encroaching businessmen while they await the return of their nephew Spencer (Brandon Sklenar) from abroad.

Still, the heart of the story, in Mirren and Ford’s eyes, is the relationship between their characters.

“These two are partners as much as lovers, and [they’re] depending on each other for things that they are not part of their quiver of arrows,” Ford says. “And it’s an extraordinary relationship that Taylor [Sheridan] has written for us to inhabit.”

Mirren agrees. “It’s rare to see. In movies, people get married or they meet-cute and they fall in love and they have hot sex or whatever, and then it’s all over, happily ever after. Well, this is the ever after. Now we’re seeing what happens at the end of that story, and you very rarely see that onscreen.”
