Mitchum died Sept. 20 at his ranch home in Skull Valley, Arizona, after a long illness, a family spokesperson announced. He also had a part in Dennis Hopper’s critical and financial disaster The Last Movie (1971) and made a short documentary about the experience working in Peru with Hopper, Peter Fonda and Kris Kristofferson called The Last Movie Movie. Mitchum’s mom was determined to keep him out of show business as long as possible, but when he was 16, he was cast as Robert’s younger brother, Robin Doolin, in the cult classic Thunder Road. Also produced by Robert, the movie, about Southern whiskey runners pitted against federal agents and organized crime, was filled with car chases and stunts.
