What I've learned being a writer is to just basically not buckle - not be belligerent, not be angry, not throw fits. Though there are times where you have to stand up and yell. If I've got to throw a chair, I'll throw a chair. There was a meekness about me when I started, and I think the meekness has sort of evaporated. I hope that it's left behind a more passionate person, not a meaner person. So I guess that's what I've learned.

When you only have $15 million, you have to talk about something interesting. You can't just cut to a helicopter exploding.

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.

The other thing being at UCLA was just being in California and around the movie business. Which I honestly believe, and I've told this to screenwriters, you have to do. You have to be there in order to write or direct movies.

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.

Going to UCLA, as far as I'm concerned, afforded me two things. One was the advantage of meeting friends and getting to know a group of guys I hung out with, was chummy with. All of us eventually had success with film. Making films, cutting our own little movies together, 3 in the morning going out and shooting stuff, finding gels that people had thrown away, making our own lights. It was like a frat house for film geeks, the Pad O' Guys. That's what being at UCLA afforded me.

I have no power, and that's what's so humbling.
