I was kind of scared at first to do that [vice-over] because when you're on set, a lot of the things going on around you - the environment and playing off other actors - and that's what makes it easier and helps you to be in your character. So, realizing you're not going to have that and you're going to be secluded in this booth, it's like, "How am I going to be a character when I'm just in these walls?"

What's the best part of a movie? I love to know what my name is. It's just so fun. That's the first thing I ask. It's just fun because you have a different name in every movie.

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 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.

I always wanted to be a part of Nicolas Winding Refn world, but knew he would never make a movie that has a teenage girl as a lead. Obviously not. Then I heard he was and it was in the fashion world. What? Just combining what we think of [with Refn] - masculinity and violence - in his films with that world was so interesting to me.

I would love to work with my sister in a movie one day - like play sisters or something like that, because we've never been on-screen at the same time together.

The hardest thing that I'll ever do, is ballet. Because you are either good or bad.
