27. Only two films have won three acting Oscars -- "A Streetcar Named Desire" and "Network." None have won all four.
28. Before Hugh Jackman, only one Best Actor nominee in the last thirty years had been nominated for starring in a musical -- Johnny Depp in "Sweeney Todd" (the last before that was Roy Scheider in "All That Jazz"). And no actor has won for a musical since Rex Harrison for "My Fair Lady" in 1964.
29. Only one actor has even been nominated for Best Actor and Best Supporting Actor in the same year, for the same performance -- Barry Fitzgerald, for "Going My Way" in 1944 (he won Best Supporting Actor, while Bing Crosby took Best Actor for the same film). Two actors -- Al Pacino and Jamie Foxx -- have picked up nominations in both Best Actor and Best Supporting Actor in the same year, but for different performances. Both won Best Actor.
30. None of the Best Actress nominees have won an Oscar before, the only category this year in which that's the case.
34. At 9, she's also the youngest ever nominee for Best Actress
35. At 85 years old, Emmanuelle Riva is the oldest ever Best Actress nominee.
38. Amy Adams has four Best Supporting Actress nominations and no wins. She comes second to Thelma Ritter who had six nominations in the same category without a win.
39. Jessica Chastain is the only acting nominee this year to have also been nominated for a performance last year (though Clooney had acting and screenplay nominations last year, and Best Picture this year). She's got a way to go before catching up with the record shared by Bette Davis and Greer Garson; they each managed five nominations in a row, from 1938 to 1942 for the former, and 1941 to 1945 for the latter.
40. John Williams' nomination for his "Lincoln" score was his 48th; the most for a living person.
