I love people like Renée Zellweger who aren't afraid to look unattractive and really put themselves into a character role and to really be an actress instead of just thinking "Am I on-screen pouting and looking beautiful?" because that's not really what it's about.

The character is everything that I felt really strongly against - she's superficial, materialistic, vain, amoral. She's all of these things, and I realised that I really hated her. How do you play someone that you hate? But I found it really interesting and it gave me a whole new insight into what my job, or my role as an actress, could be.

Girls should never be afraid to be smart

All the baggage that comes with fame, being an actress. The down side to it is the intrusion into your life and this expectation that because they've seen you onscreen, they kind of have a right to you as a human being and personally and in your life.

It's quite stressful knowing that every time you walk out the door, someone is going to be giving you a very good look up and down, judging everything you wear.

In Cancún, I felt like I had walked into an American teen movie.

As wonderful as charity is, that money runs out. It's not sustainable. It lasts for a certain period of time and it's gone. What i really think people need is the opportunity to help themselves.
