Four years before the Zodiac Killer befuddled California police in David Fincher’s Zodiac, co-writer and director Bong Joon-ho brought South Korea’s first serial killer to the screen in 2003 with Memories of Murder. Bong was building a storied career in his native Korea before the director was formally introduced in the United States with Snowpiercer (2013), Okja (2017), and Parasite (2019). Memories of Murder, only his second feature film, is an instant classic.
