On the Basis of Sex (out Feb 7) follows on from last year's successful documentary about iconic U.S. Supreme Court justice Ruth Bader Ginsberg (RBG) and is a dramatic biopic that focuses on a particular case argued by Ginsberg (played by Felicity Jones) that sought to change the laws regarding gender-based discrimination. This is an interesting, eye-opening story with Jones astutely portraying Ginsberg as a determined, passionate woman. Grade: A-.
