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.

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.

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.

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.

It's all about human condition, ultimately. That's what you're looking at. You're also looking to have some fun, as well, because that also translates. Maybe wearing tights once in awhile helped. Getting up on a horse a couple of times before might have helped.

I can only put myself in the process and try to learn through the process. Sometimes it will go well and sometimes it won't.

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.
