That performance earned him the Academy Award for Best Actor.
Despite the enormous differences between those characters, Duvall brought the same quality to each of them: authenticity.
His characters rarely felt like performances. They seemed to arrive on screen carrying lives that had begun long before the camera started rolling.
Across his career, Duvall worked extensively in film, television, and theater, earning seven Academy Award nominations and winning once. He remained active well into old age, continuing a career that had begun with his memorable film debut as Boo Radley in *To Kill a Mockingbird*.
His wife, Luciana Duvall, remembered the commitment he brought to his work, saying that he gave himself fully to his characters and to the human truth behind them.
Following his death, fellow actors and filmmakers including Al Pacino and Francis Ford Coppola paid tribute to his extraordinary talent and the authenticity that defined his performances.
