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.

If an actor commits properly to a role, they do a bit mad during a shoot. If they're going to do that, they should balance themselves by doing a role as a yoga teacher.

It's part of developing the whole state of how cinema is; everyone is looking out and engaged rather than it being just a financial thing or sitting back, waiting for scripts to turn up.

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 think CGI is interesting but it's too expensive and limiting in terms of what you can do shot-by-shot.

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.

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.
