Watch Felicity Jones as young Ruth Bader Ginsburg in 'On the Basis of Sex'

Neil Gorsuch (and possibly Brett Kavanaugh) may be the new flavor on the U.S. Supreme Court. John Roberts may be its chief justice. But when it comes to pop-culture icon status, nobody on the high court can compete with Ruth Bader Ginsburg.

The justice, who will mark 25 years on the Supreme Court this August, has inspired two movies: "RBG," a documentary released in January, and December's "On the Basis of Sex," a biopic for which the trailer debuted Monday.

The "Basis of Sex" trailer features Oscar nominee Felicity Jones ("The Theory of Everything," "Rogue One: A Star Wars Story") ditching her British accent in favor of a Brooklyn one as a young Ginsburg.

We see Ginsburg, first as a young wife and law student at Harvard (and later Columbia), then struggling to land her first job, and later furthering equal rights through key legal victories in the 1970s, aided by her husband Martin Ginsburg (Armie Harmmer).

Though many of her court victories benefited women, the film's title is actually drawn from the argument she made on behalf of a male client named Stephen Wiesenfeld, whose wife died in childbirth. In 1975's Weinberger v. Wiesenfeld, she convinced the Supreme Court that the Social Security Act unfairly discriminated on the basis of sex by denying widowers like him their late spouses' death benefits while providing them to widows.

An interesting footnote: Forty years, later Ginsburg later officiated Wiesenfeld's wedding when he remarried in 2014. We kind of hope that part's in the movie, too.
