What I love about Neill's Blomkamp work is that his stories are small human stories. But what's interesting about Neill's movies is that they're set in the future but they're so incredibly timely that it feels like maybe in the present in the next dimension. It feels like it's happening now. The universe is very recognizable, in many ways.

I think I have always tried to do the smaller films. I like to jump around and there is something really nice for acting in a smaller film... But I think now, Hollywood's movies certainly involve a younger generation for the most part and so... I love going back and forth.

I'm no Ripley. I had doubts that I could play her as strongly as she had to be played, but I must say that it was fun exploring that side of myself. Women don't get to do that very often.

Every role sort of teaches you how to prepare for it.

I changed my name when I was about twelve because I didn't like being called Sue or Susie. I felt I needed a longer name because I was so tall. So what happened? Now everyone calls me Sig or Siggy.

I often meet young directors who, you know, had a 'Ghostbusters' picture on their wall as they were growing up. And it's really nice. It just shows how inter-generational our industry is.

When I was in college, I was an English major, but I was part of this great group at Stanford called the Company. We didn't know any better, so we did it all; we did King Lear, we did Hamlet, new plays ... And we did it all in a covered wagon that we took around the Bay Area. We all put our makeup on in one cracked mirror. It was the most fun I've ever had.
