I genuinely try to make movies I'd want to go and see, movies that are a bit more challenging.

People say, "How do you get into the British film industry?" There is no British film industry, there are just people making films and finding their own way. It's not like in the States where there are studios and there's an actual infrastructure to it; there's just nothing here. You make it from scratch a lot of the time.

The only genre I have any problem with is musicals, but that's just my own tastes it's nothing to do with the films.

I like that confusion when people are speaking in the same language but still can't understand each other. It's also usually my experience of being in America - when I speak no one can understand what I'm saying.

Sometimes my scripts get so dissolved, and they're so different from when I wrote them originally, that I find it hard to find what I wrote in it.

I tend to shoot really quick so you don't get the problems you might get on a traditional film where you shoot one way, then another, and it's pissing down with rain and they won't cut together. We shoot so fast we can incorporate the weather into it. The worst weather we had was when they were in the caravan up the mountain and there was no cover. One man's weather is another man's production value. To create the sleet would cost a fortune but we got it for free so we'll just have to go with it.

Lots of crime films are about work. Free Fire could have been about a company of plumbers doing pipe-fixing and stuff. But the plumbing film is not so exciting.
