Nothing that new with the exception of some small casting news in regards to the other main character but The Great Gatsby and Carey were mentioned in a recent interview with director Baz Luhrmann You can read the rest of the interview with Baz Luhrmann at the source.
“I’m so thrilled about Carey Mulligan [who's been cast as Daisy]. She’s just fantastic, and now one has to match Jordan. They’re a couple in a sense. They reflect two completely different sides of a coin. And so the role of Jordan has to be as thoroughly examined as Daisy, for this production, for this time,” he tells EW. “It’s like Olivier’s Hamlet was the right Hamlet for his time. Who would Hamlet be today? Same with a Jordan or a Daisy” He doesn’t yet have a short list. “I’m seeing everyone,” he says. “What’s crucial about Jordan is that she is incurably dishonest, to quote Fitzgerald. She’s dishonest on an internal level, and she has an inability for self-realization. She’s a dangerous driver, to quote Fitzgerald again. And in the simple language, I think Jordan is also what, at the time, you might have referred to as a Long Island flapper, and now you might refer to them as a Hamptons flapper. That just means not a bohemian flapper that’s living the Village, but someone who’s attaching themselves to the fashionable aspects of flapperdom…. I don’t take it lightly at all. It’s my obsession at the moment. The connectivity between buying into, in a fashion sense, this new movement — a new liberation of women, a new sensibility, a youth that was absolutely drunk on money and possibility, the first ever American youth that was completely youthful — that is a thrilling subject.”
