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.

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.'
