I don't regret anything. I feel like I've made what I would call mistakes. I picked the wrong movie, or I didn't pursue a character, but everything you do is part of you and you get something from it.
Playing a character is an illusion, and I feel that when you know too much about a person, possibly part of that illusion is disrupted.
It would be hard to play a character you don't like - for me anyway - or can't find something in them to like.
Responsibilities are relative. My responsibility is to a character in a script, to a part I'm playing.
I'm an actor, and everything about me - the way I perceive things, the way I have seen the world - has been in relation to characters and how I would want to play something or not play it.
I do believe, and I will always believe, that Shakespeare on film is really something that should be tried more often because it is an opportunity to take the humanity that Shakespeare writes into characters and express it.
