Can't really say I'm surprised. If you pay attention to the awards seasons, typically the people who win all the guild awards (Screen Actor's, Writer's, Producer's, Director's, etc.) also win the Oscars. So when Jamie Lee Curtis won the Screen Actor's Guild Award I had a feeling she was gonna win the Oscar as well. And sure enough...
I was more surprised because she lost the Golden Globe, Critic's Choice and BAFTA, and she's definitely not the better Supp. Actress nominee from Everything, Everywhere. I'm glad she finally has an Oscar, but I do wish Stephanie Hsu had won instead.
I know this movie has been beaten to death on the Internet enough times already but... I don't know what the people behind Emilia Pérez have on Hollywood to make it this prominent during the awards season. Because my god that movie is AWFUL. One of the worst Best Picture nominees I've ever seen in my life and it's still astounding to me that it did so well.
