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.

Merlin is really at the forefront, in that regard. We get a glimpse into the dark, Machiavellian corridors of power. I like the fact that, although he has powers, his powers are almost in his political guile as much as what he relies on, in darker forces.

From the age of about five to twelve I was very bad, a hideous little terror who beat people up. I was a member of a Rough Gang - we went around and terrorised all the pupils in school.

I fall in love with contradictions without understanding. I can't really portray them unless I do. So in a roundabout way I have to fall in love, it's my duty. If love is about understanding and understanding is compassion and compassion is love, I have to have compassion towards the world.

It's all about human condition, ultimately. That's what you're looking at. You're also looking to have some fun, as well, because that also translates. Maybe wearing tights once in awhile helped. Getting up on a horse a couple of times before might have helped.

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.

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.
