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.

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.

Conditioning can be not a big heavy thing. (For instance:) I've got a brand new pair of shoes, by mistake you step on it and you make them muddy and dirty, I'm conditioned to go "Hey, what are you doing?" That's my conditioning, I have a response. So, maybe we have to learn to find the pause before we react, because reaction is our conditioning.

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.

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.

Maybe we need more dialogue in terms of our faith, in terms of those who are believers, or even nonbelievers, about that aspect, and what that might mean if you were interpreting. You don't have to believe it; maybe you could draw a metaphor from it.

Whether you're a believer or not, I think there's a huge value in understanding the quality of redemption.
