There's a picture of the real Coach Gary Gaines in the book and he's sitting in the locker room after a game, and he just looks so much like Billy Bob, that we went to him.

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 somewhere along the way became fascinated with exploring characters who are willing to put themselves into violent situations, whether it's football, hockey, boxing, being a cop, being a soldier. There's not a lot of people who are willing to put themselves into those situations.

Michael Mann's always been one of my heroes.

I think musicians oftentimes have the right skill set to be good actors. And with Rihanna, I noticed her and knew of her obviously, and was very taken with her charisma and her confidence.

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.

The first movie I literally ever made in my life was about two guys playing Stratego with each other. I had all my friends dressing up like the military characters in the game. So 'Battleship' is really my second board game turned movie!
