President Trump delivered a nationalistic cultural rant at his rally in Colorado on Thursday night, veering off script to attack the Academy Awards for giving the Best Picture Oscar to a South Korean film, “Parasite.”

“How bad were the Academy Awards this year?” the president said, throwing up his hands as the crowd roared at his rally in Colorado Springs. “Did you see? And the winner is a movie from South Korea. What the hell was that all about?”

“Parasite,” the acclaimed thriller by Bong Joon Ho about class tensions boiling over in a wealthy family’s home, this month became the first film not in the English language to win the Academy Award for best picture in the 92-year history of the competition.

The film also won best director, original screenplay and international feature, marking a moment of pride for many Asian-Americans and a turning point in the academy’s long history of embracing stories told by white filmmakers.
