Who knocked out the competition and won Best Actor for playing real-life boxer Jake La Motta in "Raging Bull"?

La Motta's life was explosive both in and out of the ring, and De Niro's portrayal brought him his first Best Actor Oscar and second Oscar overall. He previously won Best Supporting Actor for his role in "The Godfather, Part II."
