I had my group of friends, and they stayed my group of friends, they were good about that. We all started to succeed at the same time, so that sort of took the curse off it. I didn't have a bunch of people scowling at me and being potentially jealous. I just had good friends who I was able to help, and they helped me. Yet it eventually came to feel debilitating.

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

Sometimes I'll have a scene that strikes me, I just feel like writing a scene, a mini-story that seems like it might lead somewhere. But that is such a tentative, fishing-hook way to go about it that these days I've found it's easier to kind of at least have your concept and start attaching things to a skeleton. So I try to find the armature, the kind of backbone of it first that you can start to hang those scenes on.

I think the most important thing is to, without belligerence, stand up for what want. Argue compellingly if someone tries to change your script. Yeah, legally they can if they want to. But rather than give up, as some of the writers do, and just wail about how your script got rewritten, it's much more difficult - but well within the realm of possibility - to argue very sincerely, calmly, and reasonably from your point of view, such that the director or the producer might decide, "All right, let's do it that way."

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.

Every director should take an acting class. At least one. You know, you panic with actors. It's like, "Okay, this is back in college, I know how to talk to these guys. I know their vocabulary, and I get what they're saying back to me." So basically to learn the vernacular of acting, that's very important.

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.
