Copa 71: when 112,500 fans packed out the unofficial Women’s World Cup final

The tournament in Mexico has been all but forgotten about for nearly 50 years. A Venus and Serena Williams produced documentary aims to correct the record

Brandi Chastain is the star of the opening scene of Copa 71, a documentary poised to change how the history of women's sport is remembered. Chastain is not talking about her famous moment in 1999, when she ripped off her shirt to celebrate winning the World Cup for the United States in front of 90,000 fans at the Rose Bowl.

Instead, Chastain is seen watching footage of another match played in front of a packed stadium. But she is trying to guess which one. That's a massive stadium ... that's a men's football match ..." She stops as she sees the players.
