The great thing about films is that you have access to this whole world of experts who teach you the skills your character's supposed to have.

I like the fact that we're stripping the icons away. They're the WikiLeaks for the age that we're revealing, with the transparency of the characters. We're unearthing the truth beyond or underneath the myth. I love that aspect.

But it's a strange thing when people judge you because you're not doing some big Hollywood film. Are you suggesting I should be in The Dukes of Hazzard? I mean, hello?

A large part of how an actor works and their process is the stimulation of what's around you, and none more so than in a period piece. This is a modern piece, as much as it is set in a different time, age and myth. If it wasn't relevant, it wouldn't have been made and we wouldn't be putting our energy into it. It's relevant for us today because, in some ways, it throws up a mirror to all of us. As an actor, you get stimulus and you're effected by that, whether it's costumes or funny beards or castles.

There are a couple of films that I've done, where I've had to get on a horse and wear a pair of tights, so that helped. But, nothing could have prepared me for the fun of wielding magic like Merlin does, especially in the perverted mind of Chris Chibnall.

Maybe we need more dialogue in terms of our faith, in terms of those who are believers, or even nonbelievers, about that aspect, and what that might mean if you were interpreting. You don't have to believe it; maybe you could draw a metaphor from it.

I'm a huge admirer of Pope Francis and everything he stands for. I think he's an incredibly connected spiritual and authentic being.
