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.
