This year's winner for Best Actress category was unique. Although playing a supporting role and having a relatively small amount on the screen, Patricia Neal won the Best Actress category for her lead (or supporting) role in Hud. The movie also won for Best Supporting Actor for Melvyn Douglas and Best Cinematography – Black and White. It was the second and, to date, last film to win two acting awards without being nominated for Best Picture (the other being The Miracle Worker).
At age 71 Margaret Rutherford set a then record for the oldest winner for Best Supporting Actress. Coincidentally, the year before Patty Duke set a then record for the youngest winner ever. Rutherford was also only the 2nd Oscar winner to be over the age of 70 at the time of her win. The other was Edmund Gwenn.
This was the only time in the history of the Academy Awards that all Best Supporting Actress nominees were born outside the United States.
Sammy Davis Jr. announced the winner in the category scoring of music, adaptation or treatment but was given the envelope with the name of a winner in a different category (score, substantially original).
