I read as much as I could, but really just spoke to Chris Chibnall and asked all the pertinent questions. That made me feel like we weren't going to do an off-the-peg Camelot, which has been touched upon in many films and TV series before. I really just picked his brain and, in doing so, I got fired up by tackling Merlin in a fresher angle.

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.

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.

I've got a vendetta to destroy the Net, to make everyone go to the library. I love the organic thing of pen and paper, ink on canvas. I love going down to the library, the feel and smell of books.

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.

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.

he challenge is finding the modern conduit for the audience, having fun and really looking at the duality of this particular character, that is both devil and angel, and on the cusp of losing control of the pagan background, to this newfangled religion called Christianity. There's a great backdrop there, and just a whole dark side with the magic.
