James Byron Dean (February 8, 1931 – September 30, 1955) was an American actor who 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. These films include 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 released shortly after his death.
