When you read the poem, you wonder, what might Grendel have been? Could it have been a person that was turned away? Someone that was disfigured or deformed? Like everything else did, it came from somewhere. It's really exciting, and not knowing is part of the magic and mystery.

I did quite a lot of fencing when I was a kid, I was a swimmer, and I played a lot of basketball. I was a fencer for Great Britain, but I only did that because I watched Robin Hood, Star Wars, Highlander and The Three Musketeers, and I wanted to emulate Richard Harris and the great British actors that I grew up watching.

I always love being an actor for the simple fact that, whenever you do a job, you have to read a lot of stuff that you've never read before, you explore things, and generally you meet experts in lots of fields and you get to absorb that information and make it look like you've done it for 20 years.

I've been trained by a two-time world champion kickboxer, who's local to where I come from, and who is really just there to keep me fit and healthy while I'm shooting.

I come from the theater and you normally have four or five weeks to prepare. For me, the fun of the job is to pull yourself into a subject that you know nothing about.

I want to know everything. I'm probably a bit of a pest for the producers because I ask a lot of questions.

You can't go around saying you're the best, all the time, 'cause it puts a target on your back.
