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.

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

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

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.

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.

Film is more of a dream when you're younger. I found it almost impossible to see how you would get into the industry having no connections, nobody in the family being anywhere near it and never meeting anybody that had been on a set.

If you make a movie in the UK you've got to embrace the weather with open arms... We got some of the most amazing weather as well. It's maybe why some of these places, like the Lake District, don't get filmed in so much. If you were trying to make it look like some kind of chocolate box image of England you'd be there all year waiting for the sun to come out.
