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.

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.

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.

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 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.

There are a couple of films that I've done, where I've had to get on a horse and wear a pair of tights, so that helped. But, nothing could have prepared me for the fun of wielding magic like Merlin does, especially in the perverted mind of Chris Chibnall.

I think academics are infuriating. For every expert on Shakespeare there is another one to cancel his theory out. It drives you up the wall. I think the greatest form of finding out the truth is through fantasy.
