As George, a history professor whose marriage to Martha is a long night of verbal warfare, Burton gave one of his greatest screen performances.
Who’s Afraid of Virginia Woolf? (1966), from Edward Albee’s play, pairs Burton with Elizabeth Taylor as a couple who host a younger couple and dismantle each other’s illusions. Burton plays George’s wit and wounded dignity with extraordinary control, and he was nominated for Best Actor.
It is a landmark of screen acting, and Burton at his peak.
