It all felt like a terribly long time. It would have meant that I had to make five movies in five years and if you don't like the movies, too bad. I guess I just wanted my freedom, and I think my life has been incredibly enhanced as a result.

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.

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.

'How do you balance the creative with the biblical?' One could pick up the scripture and read it to oneself and you would be communing directly with that information. As soon as you go into film, as soon as there's a camera, and there's an angle, and there's lighting, and there's editing, you're into the adaptation.

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.

I also wanted to have fun with it. I wanted to have the scope, which I felt Merlin has, in his Machiavellian bi-polar way. He's not to be trusted, yet he is fighting for this great power and is really a master, to some degree, in orchestrating Camelot and King Arthur. He's a strange, dark devious character, and I just wanted to have fun, and get away from the cloak and long beard and pointy hat.
