Academy Award-winning actor, director and activist Robert Redford has died at age 89. We look back at three interviews with Redford over the years: • From 1994, with Charles Kuralt, who visited Redford's home in Utah and talked about his early career, and his advocacy of Native American art and culture • From 2006, with Rita Braver, discussing his iconic roles in "Butch Cassidy and the Sundance Kid" and "All the President's Men," and how he nurtures young filmmakers through the Sundance Institut
