The 'Bright Star' actress doesn't want to take on roles just because she knows they will be a box office hit or easy to make as she wants to improve on her acting skills.
She said: "I never take a film that is going to be a walk in the park, because I don't see the point in that.
"It's important to know what path you want to take as an artist. I want to be challenged."
Although the Australian beauty - who is dating Hollywood heartthrob Ryan Phillippe - says she has always wanted to be an actress, she also had aspirations in many other areas of her life when she was growing up.
She told Britain's Culture magazine: "I never felt like I just want to be an actor, and that's it. I always wanted to work with animals. I want to make music, to paint, to take photos, to travel. That's a lot, right?
Sometimes I wonder how I'm going to get it all done."
