Teen movies often have an unspoken underlying prem...

Hopefully with each thing that you do you're learning something, you're growing, and you're pushing yourself a little harder in some way or another. So I think you'd be in real trouble if each new thing that you create didn't feel like 'Oh, wow. I feel like I'm doing something a little different this time.'

I do love science fiction, but it's not really a genre unto itself it always seems to merge with another genre. With the few movies I've done, I've ended up playing with genre in some way or another, so any genre that's made to mix with others is like candy to me. It allows you to use big, mythic situations to talk about ordinary things.

I mean, the first 'Back to the Future' is kind of a perfect script, I think, in terms of handling time travel the best. It depends on your definition. To me, that means it effectively uses it in the story.

As a precocious teen I dreamed of being Graham Greene. Well, as it turned out, I never wrote a great novel, sadly, and I never converted to Catholicism, happily, but I did do one thing he did. That is, in middle age I moved to a seaside town and got into a right barney with the local powers-that-be.

I'm a teenager, but I'm independent - I have my own apartment, I have my own life. And I think I have learned more than any of those teenagers have in school. I learned to be responsible, leaving my family and coming here alone.

I have always had a sense that we are all pretty much alone in life, particularly in adolescence.

Being a teenager is an amazing time and a hard time. It's when you make your best friends - I have girls who will never leave my heart and I still talk to. You get the best and the worst as a teen. You have the best friendships and the worst heartbreaks.
