RBG: Hero. Icon. Dissenter.

At the age of 85, Supreme Court Justice Ruth Bader Ginsburg is a legal legend, a feminist hero, a notorious dissenter. She's developed a breathtaking legal legacy while becoming – unexpectedly – a pop culture icon. We know her accomplishments, but we've haven't heard her story. Until now.

"I ask no favor for my sex. All I ask of our brethren is that they take their feet off our necks."

With last week's release of the empowering RBG, a revelatory documentary biography that explores the esteemed Justice Ginsburg's truly remarkable life and career, from directors Betsy West and Julie Cohen and co-produced by Storyville Films and CNN Films, we are reminded of her tireless fight for women and equality – of how law can be used for social change.

"People ask me: 'When will there be enough women on the court?' And my answer is 'When there are nine.'"

In RBG, we see up close how Justice Ginsburg balances her personal and professional life. We learn of her energy, her focus, her drive – even her sense of humor. Her confirmation hearing before the U.S. Senate Judiciary Committee – she was nominated by President Bill Clinton – is an anchor and central narrative thread for the 97-minute film in which we see glimpses of both her personal and professional sides.

"I became a lawyer when women were not wanted by the legal profession."

Justice Ginsburg's professional energy is shown time and again throughout the film, of which I saw a sneak preview in a northwest Washington, D.C., theater five days before its release date in selected cities. Inside the Supreme Court Building, we see Justice Ginsburg's personal office decorated in colorful modern art. There are lots of family photographs of her and her late husband, Marty – the love of her life – as well as of her children and of her grandchildren. We see her many judicial robes and her collection of "dissent" collars. It is a wide-ranging space. We also learn about the collegiality Justice Ginsburg shares among the other eight Supreme Court Justices, regardless of their liberal or conservative leanings. For all of their differences, she was actually best of friends with the late conservative Justice Antonin Scalia.

"Men and women are persons of equal dignity and they should count equally. The point is that the discriminatory line almost inevitably hurts women."

In RBG, we learn about Justice Ginsburg's intellectual curiosity. Born in the 1930s, she was the first in her family to go to college, and was one of nine women among a Harvard Law School class of more than 500. We understand the important place she holds in judicial history in fighting for gender equality. As a young litigator, she took six gender discrimination cases to the Supreme Court – and won five of them.

"I did see myself as kind of a kindergarten teacher in these days because the judges didn't think sex discrimination existed."

Then, on August 10, 1993, Ruth Bader Ginsburg became the second female to sit on the nation's highest court. Talk about a legacy! She is a center of power on and off the court. Outside of the Supreme Court, we witness Justice Ginsburg's love of opera and the arts – and talking to groups of young school students – as something that rejuvenates her. We also see up close her regular gym workouts, doing planks and push-ups, that show how she's proud of keeping herself in shape to do the job of Supreme Court Justice.

One critic labeled RBG a love story, a history lesson, a comedy, a profile in courage. The Washington Post wrote: "She's created a whole new way for the public to look at a Supreme Court Justice."

"I surely wouldn't be in this room today without the determined efforts of men and women who kept dreams alive."

RBG is an excellent, inspiring and important film that – hopefully – will inspire generations of women to pursue law and justice. It's also an important historical document. We are reminded of Justice Ginsburg's commitment to creating a more equitable society for all people.

After all, you can't spell "truth" without Ruth.
