At the age of 85, U.S. Supreme Court Justice Ruth Bader Ginsburg has developed a breathtaking legal legacy while becoming an unexpected pop culture icon. But without a definitive Ginsburg memoir, the unique personal journey of this quiet warrior’s rise to the nation’s highest Court has been largely unknown, even to some of her biggest fans—until now.

RBG, directed by Betsy West and Julie Cohen and produced by Storyville Films and CNN Films, explores Ginsburg’s exceptional life and career as she approaches her 25th anniversary as a Supreme Court Justice.

The film gets a theatrical release in select theaters beginning May 4, so be sure to see this bigger-than-life Justice on the big screen this weekend.
