An action movie should, like any other, follow the narrative traditions of literature. That means there should be subtlety, a slow build and a gradual bringing together of all the separate threads of the plot. To see all of it coming together slowly is very rewarding for the audience.

The worst of the action films are the ones where everything is one shout from beginning to finish. And there's no differentiation between beats, like small or big, or quiet or expansive. It's all just one loud shout.

I wanted at one point to act, which is a weird thing for men to want to do. It's a very vain profession.

An action film can have too much action; picture an equaliser on a stereo, with all the knobs pegged at 10. It becomes a cacophony and is, ultimately, quite boring.

I do think the challenge, in a way for me, is to write a narrative film and when you finish watching it you feel like it's a collage. You tell the narrative, you tell the story, but you feel like you've created this tapestry. But it also has a shape, a story. So I think there's a middle ground that I try to strike... away from where everyone else seems ready to go, which is, setup, payoff. You know, He's afraid of water, oh, and at the end he's swimming in water - oh, my God. I hate that stuff.

I thought of Joel Silver. He never changes. He's sort of the unmoving, unchanging rock of Gibraltar in the otherwise-shifting world of Hollywood. He's the same as he always was. He looks the same, talks the same, has the same enthusiasm.

Here's what I didn't know when I was starting out that I now know…I thought when you were starting out it was really hard to write because you hadn't broken in yet, you hadn't really hit your stride yet. What I found out paradoxically is that the next script you write doesn't get easier because you wrote one before…each one gets harder by a factor of 10.
