In 1973, tennis star Billie Jean King agreed to face 1940s men’s champion Bobby Riggs in what became the most-watched tennis match in history, The Battle of the sexes

This illuminating documentary goes behind the scenes to show the build-up to the event, with all the ridiculous gamesmanship put forth by the self-proclaimed “male chauvinist pig” Bobby Riggs, whilst also taking an absorbing look at the beginnings of women’s professional tennis and a feminist movement led by the charismatic and legendary Billie Jean King.
