"Live fast, die young, leave a good-looking corpse." The postwar hipster slogan that director Nicholas Ray popularized in his 1949 picture, "Knock On Any Door," applied with startling directness to Dean, who played the title role in Ray's 1955 "Rebel Without a Cause," the epochal misunderstood-youth movie. Dean died when his Porsche 550 Spyder crashed into a Ford. He became the first pop celebrity to be called "forever young." Warner Bros. released "Rebel Without a Cause," his second film, a month after his death, and "Giant," his third and last film, a year later.
