E! Online’s Mark Malkin got an exclusive interview earlier this week at the opening of the launch of the Extremely Piaget launch party, and he got some bits about Interstellar:

I’ll tell you a little bit. I’ll tell you about my character. I play a woman who is like a scientist. She’s super super smart and scientific and she’s not whole at the beginning when we see here. There’s an emotional part missing that we then wonder, ‘Does she become completed by the end? Is there that journey?’ I would say yes.

Trust me, there’s no way to over hype this film. I never talked like this about a film, but when I saw it I was like I don’t know what to do. It’s great.

Chastain worked most with Michael Caine.

There was one day we were doing a scene and they stopped and it was just Michael and I and they were changing the lighting,” she remembered. “I was of course asking him all these questions like, ‘Did you ever meet so and so? How as this experience? Tell me about this movie.’ There was a little bit of a break and he kind of looked away and I walked over to Christopher Nolan and I just went, ‘Thank you so much. I’ll remember this day forever.’ It was really special.
