I thought he won Best Powdered Wig, Court of Austria, 1785?

Which reminds me, when Amadeus won Best Picture in 1984, the Oscar producers couldn’t believe it. They were convinced Laurence Olivier had said the wrong name (A Passage to India was expected to win). But in fact he hadn’t, and that didn’t happen until Beatty and Dunaway last year.

ETA: it is really odd what sticks in my head sometimes.
