East of Eden (1955)
Dean's first major film role gave him top billing along with Julie Harris, Raymond Massey, and Burl Ives. Dean played Cal Trask, who competes with his brother for their father's love. This was the only major film released while Dean was alive. The role landed him an Oscar nomination for Best Actor, although it came posthumously. However, Ernest Borgnine won for his role in Marty.
