Director Bong Joon-Ho’s searing commentary on class struggle made history at the Academy Awards this month when it became the first foreign language film to win Best Picture.
On a memorable night, Parasite also earned Bong the Best Director Oscar and won both Best Original Screenplay and Best International Feature.
However, during a rally in Colorado the US president made his feelings clear about the film’s success.
“How bad were the Academy Awards this year?” the president asked, prompting boos from the crowd.
“The winner is – a movie from South Korea! What the hell was that all about?
“We got enough problems with South Korea with trade. On top of that, they give him best movie of the year? Was it good? I don’t know. Let’s get Gone With The Wind. Can we get Gone With the Wind back, please?
“Sunset Boulevard? So many great movies.”
Mr Trump added: “Did this ever happen before?”
Following Trump’s comments, Neon, the North American distributor of Parasite, issued a short - but sweet - response.
“Understandable, he can’t read,” the company’s official Twitter account said.
The president also aimed a barb at Brad Pitt, who mentioned Mr Trump’s impeachment trial during his Oscars acceptance speech.
“And then you have Brad Pitt,” Mr Trump said. “I was never a big fan of his. He got up, said a little wise guy thing. He’s a little wise guy.”
Parasite is one of the most acclaimed films of recent years - and has been a huge commercial success.
Bong’s satirical dark comedy veers wildly between different genres as it tells the story of an unscrupulous poor family’s often hilarious attempts to embed themselves inside the home of a rich family.
