In a very competitive race, Cord Jefferson won his first Academy Award in the Adapted Screenplay category for the dramedy “American Fiction.” Based on the 2001 novel “Erasure“ by Percival Everett, “Fiction” overcame a slew of worthy nominees such as Christopher Nolan‘s screenplay for “Oppenheimer,” Greta Gerwig and Noah Baumbach‘s bizarrely categorized script for “Barbie,” and Tony McNamara’s adaptation of “Poor Things” to take the prize.
