Ford v Ferrari
Once Upon a Time in… Hollywood
Bong Joon Ho, “Parasite”
Sam Mendes, “1917”
Martin Scorsese, “The Irishman”
Quentin Tarantino, “Once Upon a Time in Hollywood”
Taika Waititi, “Jojo Rabbit”
Looks like the first four are pretty much locked in, with the fifth spot a complete toss-up. I wouldn't be surprised to see any of Waititi, Phillips, Baumbach, Gerwig, or even Pedro Almodovar take it.
