Bong Joon Ho was the director of the 2013 Snowpiercer movie, which makes it hard not to wonder whether he was involved in the 2020 follow-up series in any capacity. Based on Jacques Lob, Benjamin Legrand, and Jean-Marc Rochette's French graphic novel, Le Transperceneige, Bong Joon Ho's Snowpiercer is relatively obscure compared to his more mainstream movies like Parasite and Mickey 17. However, it is still touted as one of his best works because of how perfectly it captures themes of class divides, social inequality, climate change, and survival.
