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?

There are always going to be times when it doesn't flow as much as you were hoping. So of course I'm going to fail. And when I do fail I hope I fail better and better, again and again. I am happy to fail.

Youth is a predominant factor. We are seeing a young King Arthur, and thereby a young-ish - as I'm into my 40s - Merlin. It was about how to tackle it, from that point view.

I guess there's nothing I don't like about Merlin, in this presentation. I love everything, even the things I find despicable and abhorrent in Merlin. They're actually a joy to ride on the tailcoats of.

He [Merlin] is slightly from another world and place, so it [challenge in bringing the role to life] is about having fun and presenting it in a new way. He's more of a politician, and slightly Machiavellian, but there's also a lovely relationship going on between Merlin and Arthur. There's so much to be had, really.

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.

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.
