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 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.

Pretty much all films I've seen that depict the life of Christ end with the Crucifixion, almost like the filmmakers don't know what to do after.

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.

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.

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.

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.
