The Harrison Ford effect is in full swing on the 1923 set.

Helen Mirren tells PEOPLE in this week’s issue that the men on the set of the Yellowstone prequel series can’t get enough of her costar — and she understands it.

“Harrison is such a bloke. He’s what in England we call a bloke,” she says. “He is a guy, and because he’s a bloke, all the other blokes absolutely love him, and quite rightfully.”

“He’s always so lovely to all the other actors,” Mirren, 79, continues of Ford, 82, who plays the husband to her character Cara Dutton on the show. “And so we do all sit in the freezing cold on set, on funny, funky, little uncomfortable chairs, and the other guys just gather around Harrison because they just want to be in his company, I think.”

“And I tag along,” she adds.

“We would sit around together and shoot the s— off-set,” she continues of their dynamic when the cameras aren’t rolling. “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. We hang around on the set and we do our thing.”

Ford, who plays patriarch Jacob Dutton, echoes her sentiments. “We had a good time,” he tells PEOPLE. “A good time hanging out together as well as working together.”

As for how he’d describe his costar, he says 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. “She’s a real cool lady.”

In the show’s long-awaited season 2, which comes more than two years after its premiere, Mirren and Ford’s characters continue to be pushed to the brink to defend their Montana ranch while they await the return of their nephew, Spencer (Brandon Sklenar).

“It gets bigger and bigger and bigger,” Mirren teases of what’s to come from the season.
