‘Oppenheimer’ stars Matt Damon, Emily Blunt ‘love living in the same building’

‘Oppenheimer’ actors Matt Damon and Emily Blunt tell Fox News Digital one thing they’ll never do together as neighbors.

The friendship dynamic between Hollywood stars Matt Damon and Emily Blunt shines not only on the silver screen but also when cameras aren’t rolling.

Damon, 52, and Blunt, 40, star in Christopher Nolan’s highly anticipated war drama "Oppenheimer" and told Fox News Digital what it’s like to also live in the same building.

Blunt, who’s married to John Krasinski and has two daughters with the actor — Hazel, 9, and Violet, 6 — said "it’s the best" having "The Bourne Identity" star under the same roof.

"We do have fun dinner parties. … I love living in the same building," Blunt admitted.

However, the "Devil Wears Prada" star revealed one thing she and Damon will never do as neighbors. 

"I've never read lines with Matt Damon, and I never will," Blunt said, laughing with Damon. 

"I don’t want your notes or your thoughts, ever," she joked.

The "Good Will Hunting" star equally enjoys having Blunt live close by and dished on something else they have in common.

"We both go to her husband for advice," Damon said. 

"We do. Everyone comes to John for advice, your wife included. ‘How do I deal with Matt Damon?’" Blunt joked.

The last film Blunt and Damon starred in together was 2011's "The Adjustment Bureau."

According to The Wall Street Journal, Blunt and Krasinski purchased two adjacent places in the most expensive apartment in Brooklyn near Damon’s nearly $17 million penthouse.

Although Blunt and Damon don’t read lines together, both stars talked to Fox News Digital about their roles in the explosive film "Oppenheimer."

Based on the Pulitzer Prize-winning book "American Prometheus: The Triumph and Tragedy of J. Robert Oppenheimer," by Kai Bird and the late Martin J. Sherwin, the film stars Cillian Murphy as J. Robert Oppenheimer and Blunt as his wife, biologist and botanist Katherine "Kitty" Oppenheimer.

Oscar winner Damon portrayed Gen. Leslie Groves Jr., director of the Manhattan Project, a top-secret program led by Murphy’s character Oppenheimer that designed and developed the first atomic bomb during World War II.

Damon told Fox News Digital how he prepared to take on the role.

"I started researching and thinking about playing this character," he began.

"It was really amazing learning about what they did and how they did it.… Gen. Groves was a brilliant guy and not well-liked at all by the scientists because there was this constant tension between the military and the scientists.… There was this real tension that I think the script… covered really very, very well."

Blunt admitted her character Kitty "wasn’t an easy woman to be around."

"She was not a nurturing mother. She was… as they said of Kitty… she didn't do small talk. She only did big talk. And that's so true of the force that she was.… She was definitely not a conformist to the 1940s, '50s ideal housewife. She was not," Blunt noted.

She added that although her character was not fit to be a mother at times, she always stood by her husband, Oppenheimer.

"She worshiped him, and she adored him… supported him and was his greatest confidant. And yet I'm sure they had a very tempestuous marriage. But it's what made her so exciting to play."

Despite Blunt’s character not being motherly, the "Mary Poppins" star proved the opposite in real life. 

Blunt recently revealed on the "Table for Two with Bruce Bozzi" podcast that she’s briefly taking a step back from Hollywood to focus on her family and raising her two children with Krasinski.

"I love my job," Damon added. "I think one thing Tom's always been good about is really expressing to everybody how much he cares about his job, and I totally agree with him and that's how Ben and I feel.
