Known for her large framed glasses and signature lace collar, the second-oldest supreme court justice Ruth Bader Ginsburg is truly notorious.

Of late, she has become known simply as RBG. But Ginsburg is much more than her look. Only the second woman to ever be elected the Supreme Court, she’s characterized by a life spent defending gender equality.

Since being appointed to the Supreme Court, she’s become a feminist icon. But in recent years, she’s also become a pop culture icon with books like Notorious RBG and most recently this year, the documentary RBG. It only seems natural that the biopic On the Basis of Sex featuring her life story would finally be made. Screenwriter (and Ginsburg’s nephew) Daniel Stiepleman adapted the script and decided to frame the story around her early career, in particular, the only case which Ginsburg argued together with her husband Martin Ginsburg in 1972 known as Charles E. Moritz v. Commissioner of Internal Revenue.

On the Basis of Sex begins with her time at Harvard Law School, where she was one of just nine women in a class of 500. Ginsburg, played by Felicity Jones, fought to be respected by her classmates and superiors all while raising her three-year-old and helping care for her husband through his cancer diagnosis.

At a recent screening of the film, there was no shortage of A-list celebrity guests including Hillary Clinton, Gloria Steinem, and Ginsburg herself. Though she loved the film, Ginsburg said that it didn’t get everything quite right.

This is what Ruth Bader Ginsburg says her biopic got wrong about her life
