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.

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 [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.

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.

You know what? Joy is the only guide. I'm going to have fun regardless.

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.

I don't know what my limitations are until I reach them. I look for the challenge.
