I wanted to say, "Hey, Pope Francis," but I cried like a baby. I was reduced to a very humble set of feelings, because it was not about what was said: There's a presence. That was a blessing for myself and my family and everyone there to be a part of that.

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?

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.

'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.

I've always believed that you shouldn't want to mend a broken heart, because that's someone you don't want to forget. Scars can be good.

So getting that balance between what is honoring scripture and the Word and also acknowledging the fact that by the virtue of putting it on film there's going to be a variation and adaptation, I mean, it's a fine dance and a balance. Our producers and directors have worked so hard to get that right and I'm really proud. I think it's a pretty good job.

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.
