Being raised in Scotland, where did you stand on Scottish independence?
I believe in Scottish independence. I voted for that two years ago and I still believe in it. It’s always been derided as nationalism, which couldn’t be further from what Scottish independence is about for me or for any likeminded people. Most people in the arts in Scotland are pro-independence. It’s liberal-minded people; there’s nothing nationalistic about voting for Scottish independence. It was an amazing time to be in Scotland when the vote was happening.
What was the shooting experience for “Dunkirk” like?
It was amazing, it was just such a beast. The fucking cast! Tom Hardy, Mark Rylance, Cillian Murphy – that alone was enough. Then there’s Christopher Nolan in charge!
How did you find working with him?
The guy is a proper filmmaker. If you have to get hit by something in shot, he’ll fucking chuck it at you! He’s not standing about at the back shouting stuff; he’s there. I’m surprised his hands don’t get in shots more often. But he also lets you do your own thing and experiment. It was amazing to see someone like that in operation. It’s such an incredible story and it was seriously special to film. If you see it, you’ll believe it. It will be an absolute spectacle.
What was it like working with Harry Styles on his first movie?
I actually didn’t do too many scenes with him, but I feel like if he wants to act, then why shouldn’t he! It’s a very brave thing to just jump straight in like he has. He seemed to deal with it all really well as far as I was concerned.
These are turbulent times for a lot of young creative people in the arts. What advice would you give them?
Don’t hesitate. As soon as you hesitate, you’re dead. The moment you start overthinking something, it’s already gone. Everyone has their own creative process and their own way of working, but it’s all pointless unless you take the jump. Dithering is a fucking killer!
Dunkirk is in cinemas from July 21
