I do tend to play characters that have a lot of costume and hair change. I sort of like the change of physicality thing.
I've never played a character that would sing.
I always had a struggle, which I still do, when you're playing a character and it's not necessarily your morals or your values. You're playing a character, but the way the media will sometimes ask you if these are your opinions, you know - they make you responsible for that, and I take issue with it because I don't believe in censorship.
