Note: The following article reveals details from the movie, so if you haven't seen Parasites, we don't recommend reading them.
Director Bong Joon Ho and filmmaker Kyung-pyo Hong built certain scenes, where there is a clear line dividing the rich and the poor - such as the line formed at the windows where Ms Park talks to the maid, Moon-gwang.
There's a collection of Alfred Hitchcock's films on one of the Park family shelves. Director Bong Joon Ho has said that Hitchcock has inspired him in many aspects of "Parasite".
After Moon-gwang is fired, Mr. Park discovers that her biggest flaw was that she ate for two people - later revealed to be hiding the man in the basement.
Ki-woo's fake diploma indicates that he allegedly studied at Yonsei University, the same university where Bong Joon Ho studied sociology.
When the Km family first introduced themselves, they drank FiLite, a beer considered too cheap. After Ki-woo and Ki-jung start working at the Park family, they drink Sapporo, an expensive beer.
When Ki-jung eats dry meat, he holds the bag with his left hand, then suddenly appears holding it in his other hand. This is a mistake in the filming, which Bong Joon Ho intentionally left to find out whether or not the fans would catch him.
Da-song's painting is not his self-portrait, but it is Geun's image.
Ki-taek discovers that he was once a driver for the Taiwanese Castella store (the traditional Japanese dessert) - the same shop that opened Geun's, for which he plunged into debt.
When the Kim family settles into the Parks home while they are not there, the music left is Gianni Morandi's "In ginocchio da te", who starred in several comedy films in the 1960s that focused on the differences between the poor and the rich .
At the beginning of the film, Ki-taek removes a cockroach from the table. By the end of the film, he was basically seen as a cockroach who smelled foul of the Park family.
