Serena Williams Narrates New Doc on Cultural, Racial Impact of 1968 Olympic Games (Video)

The year 1968 goes down as one of the most tumultuous and politically-charged in modern U.S. history.

Vietnam War casualties were at their height, protest movements raged, both Robert F. Kennedy and Martin Luther King Jr. were assassinated — and the Summer Olympic Games headed south of the border to Mexico City amid social unrest and protests in the country.

Tennis star and former Olympian Serena Williams gives viewers a special insight into that pivotal period in new NBC documentary, “1968,” showcasing how the Mexico City Games became a stage for a powerful collision of sport and politics.
