East of Eden (1955)

The template for every "Dad always liked you best" argument. James Dean's Cal is the restless son, Richard Davalos's Aron the good one, and Elia Kazan stages their contest for a cold father's approval as a Cain and Abel story set in the Salinas Valley around World War I. Dean plays jealousy as a physical ache, all hunched shoulders and sudden grins, and the film never pretends the favored brother has it easy either. Heavy, operatic and still raw seven decades on.
