So writing became a way to get to act in things that I thought were meaningful, and hopefully write stronger roles for other women.

The problem is if you play enough of parts in films that are sort of more financial products than anything or films in which the girl is a thankless, thoughtless, underwritten character along the way, you're no longer the person who had something fresh or vital to offer. I think it really does start to diminish some part of you, to put yourself through things you don't really want to be doing.

One of my favorite stories growing up was 'A Wrinkle in Time'. I loved that book.

Once you play with these scenes and you're outlining it, again and again, and telling each other the narrative, and telling it to people you know, trying to make sure that the mathematics of the story work, you feel that those are in place, and the actual writing and final draft doesn't take as long.

I'm really into rocks. I have a really serious rock collection. Rocks and feathers and shells and strange found things in nature. I have a lot of those kinds of collections.

The litmus test for whether I want to take on a role or not is usually fear. If Im afraid of it, then I want to do it.

Because we're watching so many movies and are consumed by so many stories, science fiction lets you do something a bit fresh and that hasn't been seen before.
