“THE THEORY OF EVERYTHING’s Felicity Jones stars in this impressively brainy dramatization of Ruth Bader Ginsburg’s rise to legal prominence in the 1970s. Thinkers debate with passion in Mimi Leder’s ON THE BASIS OF SEX, a knowingly old-fashioned (but far from dated) biopic of the inimitable Supreme Court Justice Ruth Bader Ginsburg. Written by Ginsburg’s nephew Daniel Stiepleman with affection for his aunt’s lifelong work on behalf of women’s rights—as well as her decidedly ennobled marriage founded on pure equality—this film (like the stirring documentary RBG) is both a welcome cinematic dissent from today’s disastrous politics and a reminder that words, paired with meaningful action, can change the world. A winning, inspirational crowd-pleaser, Leder’s film follows the early accomplishments of the young Ginsburg, beginning in 1956, when the bouncy, opinionated Ruth marches into male-dominated Harvard Law School”—Tomris Laffly, Time Out. PG-13. 120 Min.
