Marlon Brando won Best Actor at the 1972 awards, and Robert De Niro won Best Supporting Actor at the 1974 awards.
Kate Winslet and Gloria Stuart both received an Academy Award nomination each for their portrayls of Rose DeWitt Bukater (Winslett for Best Actress, Stuart for Best Supporting Actress) in James Cameron’s Titanic, but neither won.
