Fifty Shades of Grey author E.L. James has turned taboo topic S&M into brunch-time conversation.
But when it comes to talking about who will play Christian Grey and Anastasia Steele on the silver-screen adaptation of her books, this charmingly self-effacing British writer gets shy.
So why won't she weigh in on her casting choices? "It gets messy," James exclusively told E! News' Alicia Quarles at the Fifty Shades of Grey: The Classical Album event Monday night at NYC's Soho House. "You might end up with somebody else [than I originally said]."
James said she "never thought about how [my writing] would translate to the big screen."
The married mother of two said that casting for the film is a "collaborative effort" between herself, the producers, the studio and, eventually, a director.
And is she pushing for an NC-17 rating or just an R? "We haven't had those discussions yet," she said coyly.
James admitted that only at the end of December did she start to realize how big the Fifty Shades franchise had become. "I almost fell out of my chair when I got an email about film rights," she said laughingly.
While she admittedly gets a bit media-shy, James loves meeting and interacting with fans and the people who've read her books. "I love that it's brought women together," she said. "Especially some women who don't often read books. They read it, and that's fantastic."
And while James is currently busy with a book tour (including a trip to Seattle, which she's beyond excited about) and promoting the just-released EMI album of classical music (including Bach, Verdi, Debussy, Pachelbel, Chopin and Rachmaninoff) that inspired her bestsellers, she's already got her next project in mind.
"It's an erotic novel, yes," she revealed. It's actually finishing up the first book she ever wrote because, "I want to get it out of my head!"
Oh my! We absolutely, hard limit, can't wait.
