Zooey Deschanel

I grew up believing my sister was from the planet Neptune and had been sent down to Earth to kill me. I believed this because my sister Emily convinced me of it when I was a toddler. I think she'd seen Invasion of the Body Snatchers and her imagination ran away with her. There's a part of me that still believes it.

Do I sometimes hope I wake up in the morning and people are like, 'What's wrong with her? She looks emaciated.' Of course I would love that. I'm such a clothes whore, I would love the opportunity to be a hanger. But I think I'm more confident than I've ever felt in my life.

Supplying fuel for a Mars expedition from the lunar surface is often suggested, but it's hard to make it pay off - Moon bases are expensive, and just buying more rockets to launch fuel from Earth is relatively cheap.
