Aidan Gillen

It seems to me that most characters, in anything, are flawed in some way, just like most people. You look for the good in the flawed people and vice versa, and then try and make them appealing in some way.

'Heroes', 'Desperate Housewives', 'The Sopranos' - they're all very stylised. 'The Wire' is much more rooted in realism and honesty. In American television, I can't think of anything I'd rather have been in because it has got something to say and that is the kind of thing I want to do.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
