Yes, only 23 years of age for three Oscar noms. And she stands a great chance for a nom, with a clearly quite beloved film. Its very likely to be A24's number one priority this year, and we've seen how they can work their magic with the Academy.
meanwhile Jennifer Laurence is in that mother! flop
Between On Chesil Beach, Mary Queen of Scots, The Seagull and possibly Sweetness in the Belly (filming hasn't begun yet, so probably not), I'd say she's also set up nicely for another nomination in 2019, in which case she'll pip Lawrence to become the youngest-ever four-time nominee (24 versus 25). Watch out, Meryl. ;)
