Prolific documentarian Liz Garbus and co-director Elizabeth Wolff celebrate the life and legendary achievements of championship tennis trailblazer Billie Jean King with infectious admiration and gratitude in Give Me the Ball! Riggs also stirred up the backlash against ambitious women athletes by insisting they should be in the home making babies. Larry King also played a pivotal role in overcoming the prize money disparity issue, when he encouraged Billie Jean to break away from the male-dominated professional tennis circuit and start a women’s tennis tour with its own tournament. Along with King, original members Casals and Julie Heldman provide first-hand insights in new interviews, as does next-generation participant Chris Evert. There’s lively input also from Elton John, a tennis fan who developed an enduringly close friendship with King.
