Christian Grey - he isn't a real person. He's a superhero. A myth. He's like Bigfoot! He's unbelievable. He's unattainable. There's no actor in the world who could live up to that.

Because I used to play a lot of sport, I've always been in decent enough shape. When I used to get asked to do a bit of body work before a photo shoot I'd lie and say, 'Yeah, I'm going to the gym.' I literally never did anything.

Throughout Ireland, there's a brilliant community of filmmakers and actors, and I guess there was always a lure to do some work in the place where I come from.

I could eat 10 packs of Hula Hoops a day and not think about it.

I like playing characters who are fractured, broken. I find that more relatable, for some reason. I don't feel that I'm like that myself by nature, but there's just something that you can really grab hold of if people have a darkness in them, I think.
