In 1979, artists Christo and Jeanne-Claude proposed one of the largest public art installations in history: a "golden river" of 7,500 fabric-paneled gates in Central Park. Transcending controversy, it was finally completed in 2005. Renowned documentary filmmaker Albert Maysles and long-time collaborator Antonio Ferrera chronicle the artists' 26-year commitment to transform the winter darkness of the park into a garden of light and color.
