The Parasite director - whose film won gongs in four categories, including Best Original Screenplay, Best International Feature, Best Director and Best Picture - was spotted backstage at the Dolby Theatre in Los Angeles apologising to the engravers for creating a minor inconvenience.
In a video clip captured by Variety, the 50-year-old filmmaker says: "I'm so sorry for the hard work."
Bong also admitted to being surprised by his film's success at the Academy Awards.
