Damon and Casey, 48,returned to their hometownof Boston to shoot the film in 2023. However, the project almost didn’t come to fruition until Casey enlisted help from Damon’s wife,Luciana, Damon confirms. Casey asked Luciana, 48, to get Damon to readThe Instigatorsscript.

Damon notes that Luciana also served as a producer on the film, adding that “like Casey and like Ben” he “just trusts her taste.”

“So when they say something, when they dig their heels in on something — any of them do — I pay attention,” he admits. “We all have blind spots creatively or otherwise. And, when I see somebody that I agree with so much feeling strongly about something, I look really carefully at it.”

The film also starsJack Harlow,Ron Perlman,Michael StuhlbargandAlfred Molina.

“I went through Lucy,” Casey said, referring to Barroso. “Who’s way more agreeable and has got better taste than Matt does.”

“It’s true, it’s true,” Damon added.

Later in the interview, Damon shared what ultimately convinced him to take the role. “I just love the world and the characters,” he said, noting that he had also spoken with Casey and Liman about the film. “This was a very specific tone and we really wanted the movie to be fun, and fast and not overstay its welcome. So, kind of, the alchemy of all that. It felt like something I didn’t want to pass up," he added.
