In 1997, York turned his attention to the dramatic success of nonviolent conflicts. A Force More Powerful debuted as a feature-length documentary in 1999 and was expanded into a three-hour series for PBS, broadcast in the fall of 2000. This ground-breaking series, narrated by Sir Ben Kingsley and nominated for an Emmy, has been translated into 19 languages and is a staple in high school and college curricula.
