I was 12 when I did 'Super 8,' and when Dakota was 12, she did 'War of the Worlds.' Steven Spielberg was involved with both movies, so we both worked with Steven when we were 12.

We're constantly taking pictures of ourselves. It's a bit scary, because images are essentially dead, so we judge beauty on something that isn't alive.

I don't have a Facebook, I never have. I don't have Twitter, I never have. I think my parents are very protective, so they didn't want us to have any more exposure. But Instagram is a photo that you control. And you can talk to your fans, or talk about the movies you do - slices of your life. It is what you make it.

I'm only thirteen, so I have role-models! But I've sort of experienced... my sister has always been my role-model because I've always seen her. She's been acting my whole life and she's grown up on film, so it's neat for me to get to travel around and do interviews, because I've always seen her doing it.

I like necklaces that are short, the way skateboarders used to wear them in the seventies.

I would love to work with Marion Cotillard and my sister! I've never worked with Dakota before in a movie. It'd be so cool to be on screen interacting with each other one day. It will happen, I'm just not sure when.

Acting is different from dance. The black-and-whiteness of dancing is mostly about the technical form - like, this is how people have been doing it for millions of years. You can't let down those ballerinas who died a long time ago. My teacher will say, "This person would be ashamed!" And it's like, oh God. But with acting, it's different because people like something fresh. You can mix it up and create your own thing and it's not necessarily wrong.
