My mom and dad were actors when they were younger and had a horrible experience of it. My dad became a literary agent and my mom a casting director.

I'm the only kid in the world who doesn't want an eighth Harry Potter book.

The best thing I've learned is, if you're going out, never go out alone - you leave yourself vulnerable. If you've got someone else there you trust, they can say, be wary of that person. I probably used to be too trusting of people.

Personally, I prefer the dark side.

To the children who loved Harry Potter, I want to say your enthusiasm was the real magic. I so enjoyed being on the journey with you. And to the adults who bought the Harry Potter books and devoured them, I just want to say, those books were for children.

Both of my parents have been actors; there were a lot of show tunes on in the car all of the time. I grew up with that.

I think I'm always very naïve. With 'Kill Your Darlings' and 'Horns', I'm like, "Why wouldn't everybody love this?" But I guess it's going to divide people in some ways. But if you're willing to go with it and suspend your disbelief, you're going to get something amazing and something unlike anything else.
