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 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.

I do think the challenge, in a way for me, is to write a narrative film and when you finish watching it you feel like it's a collage. You tell the narrative, you tell the story, but you feel like you've created this tapestry. But it also has a shape, a story. So I think there's a middle ground that I try to strike... away from where everyone else seems ready to go, which is, setup, payoff. You know, He's afraid of water, oh, and at the end he's swimming in water - oh, my God. I hate that stuff.

It sometimes is better to write in a more directed, focused way when the pages are aimed at something already, a mission statement or a basic spine that represents the theme or the concept that you've agreed on, and writing partners are great for that because you can sit there until you get it.

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.

Writing scripts is a laborious job that can be a real pain.

Once you've got a concept and a sense of themes and what it's about, then you can start to add your plot and sort of Tetris in all of the elements that you want to see, but also attach them to something that has cohesion, like a mold.
