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.

You can just start writing, but you're gonna go off on 10 or 12 starts and weird tangents, and yeah you'll have those pages to use later - to gift wrap some fish for your mother - but either way you're gonna have pages.

When you are making a lot of money people forget you are trying to be creative and they picture you laughing all the way to the bank ... especially with an action script, automatically it gets boo-hooed as being worthless. It was very difficult to hear that sort of thing and I lost a good many friends over money issues because they didn't have money or their scripts weren't selling and mine were.

The Nice Guys movie was the first time in my career where what I wrote on the pages is on the screen. I'm more proud of it than anything else I've done. It is effectively what I wanted. If this movie's bad, it's my fault. It's not somebody else who changed or censored or edited it. This is the stuff I wanted, and that's what's on the screen, and if you don't like it, it's my bad.

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 it's very admirable, in a superhero movie, to be able to take a few risks.
