The Notorius RBG is coming to the big screen: Natalie Portman will play Ruth Bader Ginsburg in a biopic called On the Basis of Sex, reports Deadline. The film will follow Ginsburg's early career, with a focus on the equal-rights obstacles she overcame on her path to the Supreme Court. The film is based on a screenplay by Daniel Stiepleman, and though it's not clear whether Ginsburg herself is on board, it sounds like a flattering portrayal. "It's a really amazing portrait of a woman who was way ahead of her time," the editor of the website Women and Hollywood told Time previously. Production is expected to begin later this year.
