The youngest person to ever receive an Oscar was 5-year-old Shirley Temple - in 1934. (However, Shirley's Oscar was an honorary one.) The youngest actress to win a standard Oscar was Tatum O'Neal, who was 10 years old when she won the Best Supporting Actress award for "Paper Moon" in 1974. Christopher Plummer became the oldest person to win an Oscar, when he won for Best Supporting Actor in 2012 for his performance in "Beginners", at age 82. The oldest actor to win the Oscar for Best Actor was Henry Fonda, for "On Golden Pond" in 1982. He was 76.

The actress with the most Academy Awards for "Best Actress" is Katharine Hepburn, who won four of the golden statuettes (in 1932, 1967, 1968 & 1981.)

The title for the most "Best Actor." awards, though, is shared by eight different actors (Spencer Tracy, Gary Cooper, Marlon Brando, Jack Nicholson, Fredric March, Dustin Hoffman, Sean Penn and Tom Hanks) who each won two Oscars.

Meryl Streep holds the record for the most total Oscar nominations for acting, with 17 nominations (and three wins: two for Best Actress, and one for Best Supporting Actress).

The male actor with the most Oscar nominations is Jack Nicholson, who was nominated 12 times (winning three times: twice for Best Actor and once for Best Supporting Actor.)

The longest acceptance speech ever given at an Academy Awards ceremony was given by Greer Garson, when she accepted her award for Best Actress in 1942's "Mrs. Miniver." It's uncertain exactly how long she spoke - most sources agree it was somewhere between 5 1/2 and 7 minutes.
