The American actress has been lucky enough to find enormous success thanks to her roles in films like Closer and her Oscar-winning part in Black Swan. When she isn't busy working Natalie fills her time with her husband Benjamin Millepied and their son Aleph, four, as she knows how easy it is to become disillusioned in the City of Angels.

"I think Hollywood is many worlds," she told SF Weekly. "The (entertainment industry) is populated by both wonderful and less wonderful people. Depending on your environment, you can definitely feel discouraged or upset by the surroundings. Of course, you can have feelings of superficiality or emptiness or all of that, I think, and want to fill it with meaningless relationships...".

She shared these thoughts while talking about her upcoming feature Knight of Cups, in which she stars opposite Christian Bale as Rick, a successful screenwriter who's suffered the highs and lows of hedonism for too long. Natalie plays his married lover Elizabeth and approached the character as the most unique of all Rick's lovers, each with their own personalities and circumstances.

"Elizabeth's scenario is very different, because she and Rick have this real connection," the star explained. "There's the forbidden nature of the relationship, but also it's all about authenticity. She's always talking about respecting the love, and it seems to be one of the more authentic relationships, for sure."

Knight of Cups was written and directed by Terrence Malick, who shared plenty of books and movies with his star to help get her into the right mindset. They even exchanged letters in the lead up to production.

"It was actually really wonderful working with him," Natalie smiled. "He encourages you as an actor, which is very empowering to create and help imagine your own character - although, of course, he has a specific shape for it in mind, also."
