I'm not attempting to be a role model but I accept that roles I've played put me in that position. I don't feel a huge responsibility as an actress to put my young fan base first.

We assume that we've come so far as compassionate citizens of the world if we do choose to read the news, yet the attitude towards life can be one where we put blinders on and forget that there are civil wars going on. It's easy to forget that there are so many people starving to death every single day.

I've been extraordinarily successful for my age. I think for probably anyone's age, I'm very fortunate.

I loved Catwoman's sense of humor. I love how sly she is. I love how she, to use a cat metaphor, walks the fence and you don't know which side she's going to come down on. She's totally independent. And let's face it, she's badass.

I found it liberating to sing on camera. On stage, you have to indicate having a thought, and the word you are singing must indicate it as well, but on camera, you can have ideas, you can take in all the stimuli that the character would be taking in, there's a freedom you get, and you don't have the obligation to transmit each idea to the back of the house. It felt so much closer to reality for me.

A lot of people have told me, 'You're not this and so can't play that,' and I can't tell you the amount of times I've been told I'm not sexy. I don't wear my sexiness overtly doesn't mean that I can't become that girl for a role. That's what I do; I become things. Use your imagination.

My entire film career's been dependent on my ability to look unattractive.
