Even if it’s one of HBO’s shorter limited series, a la Helen Mirren’s four-part 2019 mini Catherine the Great, the TV production of Parasite would surely run longer than the film.
The Parasite TV series won’t be sequel to the story already told with so much success on the big screen, but will rather “expand” on what couldn’t make it into the movie.
Parasite’s run time is a little over two hours, whereas a limited series will afford Bong Joon-ho, Adam McKay, and the production team considerably more time to tell the story.
