And the very fact of how you speak somehow influences who you are. The way you move, the way you think, it seeps into your being, and it's quite hard to really break that down entirely.

I think doing different accents is part of the job of acting, really. It's something else that I quite enjoy the challenge of, to be honest.

We seem to spend a lot of our time in very small spaces spouting a lot of dialogue very quickly.

I often stop when I'm doing something, in the middle of rehearsals or some other job, and I try to take a minute to think "Okay, this might be as good as it gets, so drink it in, appreciate it now". So far, I've been lucky because another job has always come along to equal the last.

I always like seeing people transforming themselves, in whatever way that might be, and a different accent is part of that.

It has to be said that the bad guys are often more interesting than the good guys because you get to indulge part of your nature that hopefully gets subsumed most of the time. But I just like playing interesting characters, and variety's the spice of that, as it is with life, I suppose.

I'm quite happy to leave it still feeling that way, leave it before it starts feeling like a job. ... I have such fond memories of watching 'Doctor Who' when I was a kid and growing up, that if I've left anybody anywhere with memories as fond, then I feel like I've done my job.
