I'm a single child. I wanted a little brother or a little sister growing up, but when I think about it, I'm happy I'm an only child.

The actual, original 'Teenage Mutant Ninja Turtles,' I have vague memories of because I was pretty small, but I loved, loved, loved it. I have only those weird, visceral little-kid memories: I remember the extreme flat, two dimensional green that was their skin or the weird pizza with no sauce - it was just like yellow, drippy cheese.

In every single 'Tinker Bell' movie, I feel like there's a message that I'm proud to communicate with kids.
