How Bong Joon Ho Invented the Weird World of Parasite

Sims: So many of your films are about people contending with monsters they don’t understand. That’s going on in Parasite as well; there’s a gulf these two families can’t breach.

Bong: I haven’t heard this comment in a while! If you think about it, my films are always based on misunderstanding—the audience is the one who knows more, and the characters have a difficult time communicating with each other. I think sadness and comedy all come from that misunderstanding, so as an audience member, you feel bad—you want to step up and reconcile them. As a filmmaker, I always try to shoot with sympathy. We don’t have any villains in Parasite, but in the end, with all these misunderstandings, they end up hurting each other.
