Number of nominations: Three. Best Actress for Aliens (1986), Best Supporting Actress for Working Girl (1988), Best Actress for Gorillas in the Mist (1988).
In 1988, Weaver was passed over for two awards in the same year, after being robbed for her work as badass heroine Ellen Ripley in Aliens two years prior. It's not all that surprising, given that the Academy hasn't exactly been on the cutting edge when it comes to recognizing sci-fi flicks or boundary-pushing feminist icons, but still, as Carter Burke might say: "It was a bad call, Ripley. A BAD CALL!"
