Nolan

This film was considered a big favorite, it had 13 nominations, and it certainly had the most chances for this kind of success.
"Oppenheimer" won all the most important awards, starting with the one for the best picture, then for the best leading role (Cillian Murphy), for the best supporting role (Robert Downey Jr.) and for the best director (Christopher Nolan).

It has, by the account of many pundits, been a remarkably strong year for "Oppenheimer" with 2023 easily offering the most packed lineup of commercial and critical hits since before the pandemic.

That strength makes the seemingly unstoppable awards success of Nolan's "Oppenheimer" all the more impressive.
