I owe a great deal of thanks to this man who will be gracious enough to say I've helped him with his career and comeback, but it's every bit the opposite.

You have to keep surprising your audience.

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.

I think the most important thing is to, without belligerence, stand up for what want. Argue compellingly if someone tries to change your script.

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 always have humour in my action movies. I think characters that make jokes under fire are more real. It somehow helps put you in their shoes.

Any time anyone fires bullets in an action movie that don't hit the target it immediately undermines the movie.
