Emma Stone is Billie Jean King, the World Number 1 tennis player who fought for gender-equal tournament winnings. The electrifying tennis match between Billie Jean King and ex-champ and serial hustler Bobby Riggs Steve Carell was billed as 'The Battle of the Sexes' and became one of the most watched televised sports events of all time. The match caught the zeitgeist and sparked a global conversation on gender equality, spurring on the feminist movement. Trapped in the media glare, King and Riggs were on opposite sides of a binary argument, but off-court each was fighting more personal and complex battles. A breezy, funny film about serious subject matter, Battle of the Sexes benefits from some winning lead performances and the admirably light touch of co-directors Jonathan Dayton and Valerie Faris Little Miss Sunshine.
