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.

I'm very superstitious about going on other people's sets. You have to ask permission of the director; you shouldn't just turn up and skulk about in the background. It's very rude. You have to ask them personally. It's like a vampire being invited into a house.

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.

Society is about masks and hiding and pretending to be something that you're not and not opening up, and in acting, you do all of those things, but it also shows the performers in a very raw state. They have to literally upset themselves to get to that position sometimes. You don't need a load of people judging you or not being interested in what you're doing or being an ass on set because it ruins it.

The reality of any location in Britain being used in a TV program of a film is that something bad is going to happen! That's the nature of drama. Most of the things that get made or basically grisly detective shows about murders, accidents or medical dramas.

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.

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.
