Elle Fanning (A Complete Unknown, The Neon Demon) is an A-list actor who calls herself a "nepo sibling.” When she was just two years old, she played a younger version of her sister Dakota Fanning’s character in I Am Sam. But for someone who’s been famous for nearly her entire life, there’s a bit of mystery surrounding Elle — and that’s intentional. During the Toronto International Film Festival last September, she sat down with Tom Power to talk about her latest film, Sentimental Value, which broke applause records when it premiered in Cannes earlier this year.
