James Byron Dean was an American actor. He became one of the most influential figures in Hollywood in the 1950s, despite a career that lasted only five years. His impact on cinema and popular culture was profound, even though he appeared in just three major films. Rebel Without a Cause (1955), in which he portrayed a disillusioned and rebellious teenager, East of Eden (1955), which showcased his intense emotional range, and Giant (1956), a sprawling drama, have been preserved in the United States National Film Registry by the Library of Congress for their "cultural, historical, or aesthetic significance". He was killed in a car accident at the age of 24 in 1955, leaving him a lasting symbol of rebellion, youthful defiance, and the restless spirit.
