Every movie has its own unique series of challenges.
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 wanted to do a naval film and I flirted with different ideas, most of which ended up being too intense. So when the idea of 'Battleship' was first suggested, I was instantly drawn to the challenge - could I invent a movie around the idea of five ships fighting five ships?
