There's no hidden agenda, no political agenda [in Patriots Day]. The only politics we were really talking about was the politics of community, the politics of social love.

I have a tradition of working with actors, over and over again. I've worked with Jason Bateman, over and over again. You get to know an actor, and you get a certain trust and a comfort, and you become really good friends, and you feel like you've got a short-hand.

I think the biggest challenge was being aware of a certain audience that was going to see this film [lone survivor]. There's a big difference from a typical movie, journalists and critics and film goers that go see it find that, that's the general experience you have as a filmmaker. So that just kind of proves my point that there's a really different audience.

I had great luck with Tim McGraw twice in 'Friday Night Lights' and 'The Kingdom.' I love finding off-beat casting and finding someone you know in one way and you reinvent them in another way. I like doing that as a director.

I was in New York 9/11. Mark's [Wahlberg] from Boston, flew there immediately after. I was in Nice Bastille Day when the truck drove through and killed all these people. It's the new reality, unfortunately. The idea of trying to explore how we process this kind of event, how we survive emotionally, what we tell our kids: That was the movie [Patriots Day] we wanted to make.

I try to preload as little as I can. I like to come to the set with minimal preparation.

You know to me, being a good actor, the most important quality is you've got to love to play, and to just be open to anything.
