Redford's vision boosted independent films and voices beyond Hollywood

LOS ANGELES (Reuters) -In 1981, Robert Redford launched an experiment when he invited the makers of 10 low-budget movies to what film critic Roger Ebert described as a "cinematic summer camp" in the Utah mountains. Four decades later, Redford and the annual Sundance Film Festival that he founded are being celebrated as the foremost champions of independent films. Redford died on Tuesday at age 89.
