I wanted at one point to act, which is a weird thing for men to want to do. It's a very vain profession. I don't mind women who want to act. That's fine. It's odd that men want to act, in that there's still a degree of vanity associated with it. It's like, "Put on some makeup, make me look good. Okay, now I'm going to roll my shoulder." Part of me still feels like, "Wow, that's weird for a man to do."

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.

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.

Once I started selling scripts for a great deal of money - action scripts, no less, which people tend to pooh-pooh anyway - then I started to get some backlash. Which I didn't mind.

I think a lot of people - by the time I came back with a script I liked, which took me many years, they'd forgotten who I was. Doors all the time are slamming, you meet friends that you've had for years, you'd go to the studio, and they'd say things to indicate clearly that they hadn't read it, or that they'd had their assistant sort of skim it. They wouldn't buy it. They wouldn't make it.

It really started after The Long Kiss Goodnight sold for just a sinful amount of money. People were angry that I took the money. People offer you $4 million for a script - what are you going to say? "No, I'd rather sell it for $100,000"? But it engendered so much anger, I lost friends over it. And no one talked about the creative content of anything I did any more. They all just assumed I was this guy with a formula, a hack formula.
