I always found the extraordinary loss of life in the First World War very moving. I remember learning about it as a very young child, as an eight- or nine-year-old, asking my teachers what poppies were for. Every year the teachers would suddenly wear these red paper flowers in their lapels, and I would say 'What does that mean?'

Heath Ledger's performance in 'The Dark Knight' quite simply changed the game. He raised the bar not just for actors in superhero films, but young actors everywhere; for me. His performance was dark, anarchic, dizzying, free, and totally, thrillingly, dangerous.

It's like playing tennis, you play a different rally with different people. Every actor is different and the chemistry between actors is different.

I'm an eternal realist and the success rate for being an actor is pretty low.

Aircraft do not crash of themselves. They come to grief because men are foolish, or vain, or lazy, or irresolute or reckless. One crash in a thousand may be unavoidable because God wills it so - not more than that.

The acting part of me is not me. The music side is who I really am and what I want to talk about. It'll be hard for people to differentiate those different sides but I think it's possible. Once the music is out there, people will start to realize how serious I am about it rather than, 'Oh god, another actress making an album.'

Being a Christian means accepting Christ as your savior, your God. That's why you are called a 'Christian.' If you remove Christ, there's only 'ian' and that means 'I am nothing.'

A lot of stuff doesn't faze me. I think it's because I was brought up in a small town, and normally, when you're from a small town, when you see a famous person, you'd be like, 'Oh my god. This never happens,' but I've always kind of been like nonchalant.
