Watch Jessica Chastain Tease Interstellar: "It's Definitely A Love Story"

Exclusive! Oscar nominated actress dishes on the Christopher Nolan movie

We can't wait to see Interstellar.

Director Christopher Nolan's latest film (in theaters Nov. 7) has been shrouded in so much secrecy.

But little by little, we're finally hearing tidbits about the movie, which stars Matthew McConaughey, Anne Hathaway, Jessica Chastain, Casey Affleck, Michael Caine and more in a story about the discovrey of and the voyage into a wormhole in space to help save an environmentally destroyed earth.

I caught up with Chastain for an exclusive interview earlier this week at the opening of the launch of the Extrememly Piaget launch party and opening of the French jewelery house's new flagship store on Rodeo Drive.

"I'll tell you a little bit," the Oscar nominee teased. "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."

It may appear to be a sci-fi flick, but Chastain said, "It's definitely a love story, definitely a love story. As much as the film is about outer space and like the most incredible action, adventure, epic, epic film, it's so much about love.

"Trust me," she continued, "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."

Chastain looked gorgeous at Piaget. She was wearing a coral Chrisian Dior dress with fluorescent pink Louboutin heels along with a gold and turquoise necklace featuring 10.92 carats of 445 brilliant-cut diamonds priced at more than $100,000!

Also at the event were Game of Thrones' Natalie Dormer (more on her later!), Dianna Agron, Elisabeth Rohm, Eva LaRue, Sasha Pieterse and Meta Golding.
