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.

I remember a conversation with my parents about who the people on the TV were, and learning they were actors and they acted out this story and just thinking that was the most fantastic notion, and that's what I want to do.

I've always been a geek and slightly awkward… slightly umm… I was never the cool kid at school.

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.

How galling to watch someone who looks like you, who basically is you, do all the shagging you didn't get to do.

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.
