Of the 20 non-gender specific categories, women were contenders in 17 of them; they were shut out of Original Score (5 men), Sound Editing (9 men) and Visual Effects (20 men). As you can see below, 47 women other than actresses were nominated at the 90th Academy Awards. Of these, only four won Oscars. By comparison, 151 men other than actors were nominated and 32 took home Oscars.
Only one category — Costume Design — had more women contending then men but the winner was a man: Mark Bridges (“Phantom Thread”), who also picked up the jet ski for the shortest acceptance speech.
