I think I'm drawn to more villain-type characters because it's so cool to get to say all the things you want to say. In Hollywood you get to this position where you have to bite your tongue so much. You take all your experiences of not being able to say what you really want to say and channel that through your character.
I never expected any sort of success with 'Mockingbird'... I sort of hoped someone would like it enough to give me encouragement.
