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.

Self-indulgence is something to watch, but anything that helps you understand situations that are difficult to understand is good. If you're having some sort of emotional trauma, you need to find a person to talk to about it who says, 'This is quite normal; it's fine.'
