The Chaser

The Chaser (Korean: 추격자) is a 2008 South Korean action thriller film starring Kim Yoon-seok and Ha Jung-woo. It was directed by Na Hong-jin in his directorial debut. Inspired by real-life Korean serial killer Yoo Young-chul, certain scenes were shot on location around Mangwon-dong in the Mapo District, Seoul. Labeling it a "thrilling and inventive action movie", American entertainment publication Collider has considered it one of the most disturbing South Korean films of all time.
