The Best Supporting Actress category loves newcomers. Since 2000, when all five women in this category scored their first-ever nomination, more than half of the nominees have been first-timers; only once, in 2013, did the Academy select five veterans. This year, eight-time nominee (and 1998 winner) Judi Dench is joined by four actresses enjoying their first taste of Oscar attention. Three of them (Jessie Buckley, Kirsten Dunst and Aunjanue Ellis) play mothers, another Oscar favorite. Ariana DeBose holds a rarer distinction: She is nominated for playing a role originated on screen 60 years ago by Rita Moreno, who became the first Latina actor to win an Oscar in the 1961 West Side Story.
