Did some quick googling, and besides shattering the longstanding bias against international features, this would also make Parasite only the second Palme d'Or winner to get BP from the Academy, the first being Marty in 1955, just one of many reasons this was such a long shot in my mind. For the Academy to go this left field, even when it was so obvious a choice was still refreshing.
Massive wins for Bong who clearly wasn't expecting any of them beyond International Feature. I'll be curious to see what this does for Korean cinema at large in mainstream American circles. Just awesome vibes all around, from an award ceremony that let us down so badly last year.
