‘The Battle of Sexes’ explores Billie Jean King’s challenges – on and off the court

The so-called “battle of the sexes” tennis match, between women’s champ, Billie Jean King, and aging former men’s champ, Bobby Riggs, was an insulting stunt when it happened in 1973.

The movie “Battle of the Sexes.” starring Emma Stone as King and Steve Carell as Riggs, isn’t a stunt and it’s only mildly insulting. But it’s certainly a missed opportunity.
