Best Original Screenplay: Sarah DeLappe and Kristen Roupenian, “Bodies Bodies Bodies”It’s been an excellent year for the whodunnit genre, and while Rian Johnson’s “Glass Onion” is soaking up most of the late year praise, Halina Reijn’s “Bodies Bodies Bodies” is just as smart and decidedly more vicious. The screenplay by Sarah DeLappe from a story by Kristen Roupenian is a witty and biting send-up of the murder mystery and slasher genres, in which a bunch of rich, entitled Millennials try to figure out who’s killing them off one by one in the middle of a hurricane, only to discover that their worst enemy is their own shallowness.Best Actress: Anna Diop, “Nanny”Nikyatu Jusu’s “Nanny” was the first horror movie to win the Grand Jury Prize at the Sundance Film Festival.
