The trailer of the upcoming movie On the Basis of Sex based on Ruth Bader Ginsburg-- the second female Supreme Court Justice of USA--is out. Hollywood star Felicity Jones aptly plays the young justice. According to Variety, Ginsburg successfully argued before the American Supreme Court in 1975 that a widower who denied his wife the survivor benefits under Social Security violated the right to equal protection.

"If the law differentiates on the basis of sex, when will men and women ever be equal?" she asks in the trailer.
