WASHINGTON Supreme Court Justice Ruth Bader Ginsburg may appear on the big screen in a cameo for an upcoming biopic on her early career.

Stephen Root, an actor in On the Basis of Sex, told The Hollywood Reporter that the high court justice recently filmed a brief appearance on a set of courthouse steps. The filming occurred in November, according to The Associated Press .

The movie, directed by Mimi Leder and written by Ginsburgs nephew Daniel Stiepleman, stars Felicity Jones as a young Ginsburg, working on what would become a landmark gender discrimination case. It also chronicles Ginsburgs relationship with her late husband Martin Ginsburg, played by Armie Hammer.

A spokeswoman for the Supreme Court declined to comment. A spokesman for Participant Media, a production company for the movie, said the film is unfinished and wouldnt elaborate.

The movie, out later this year, is one of two recent big screen projects featuring the justice and cultural icon sometimes dubbed the Notorious RBG. An eponymous documentary about her, which premiered at the Sundance Film Festival in January , will land in theaters in May before airing on CNN .

Ginsburg, a noted opera and theater fan, has also previously appeared on stage in several operas , as well as a cameo during a 2016 production of Shakespeares The Merchant of Venice playing a judge.
