Elle Fanning on Why She Doesn't Go By Her Real First Name, The

Plus, all about her shocking new film, The Neon Demon
It's safe to say you've never seen Elle Fanning quite like this before. In The Neon Demon (out today), 18-year-old Fanning plays Jesse, an aspiring model who moves to Los Angeles only to discover that a group of beauty-obsessed women will go to any lengths necessary (and boy, do we mean any) to get what she has. While the film is aesthetically stunning, it's also hard to watch, given the dark subject matter. But Fanning—no surprise here—is a revelation as always, rising to the challenge and pulling it off beautifully. In real life, the recent high school graduate (It was a big [moment] and it's very exciting! she tells Glamour) is light, cheery, and full of laughter. But it's obvious that the movie's theme weighed heavily on her, and she came away with a deeper understanding for what it means to be beautiful and confident in today's world. So what's her advice? And which Oscar-winning actress did she talk with for guidance? Here's what Fanning had to say about all that and more.
