Operation Chromite , directed by John H. Lee, is based on the real events of the Battle of Incheon during the Korean War in the 1950s. But it actually is an artistically reinterpreted version of the real American military intelligence operation which happened before the historical landing at Incheon.The action of the movie takes place in 1950, some months after the North Korean army, backed by the Soviet Union and Chinese communist troops, have occupied most of South Korea. American war hero General Douglas MacArthur (Liam Neeson) devises a secret plan to land massive UN forces behind enemy lines at the port city of Incheon. MacArthur orders a spy operation to extract vital information from within occupied Incheon in coordination with a South Korean clandestine operation named “X-Ray”.South Korean intelligence officer Captain Jang Hak-soo leads a group of eight operatives who are impersonating North Korean officers and soldiers in order to infiltrate the enemy’s Incheon headquarters commanded by a protege of North Korean dictator Kim Il-sung – high ranking officer Lim Gye-jin,.Lim quickly becomes suspicious of Jang’s so called “inspection mission” and quietly orders his his staff to keep an eye on the new suspicious “comrades”.South Korean actor Lee Jung-jae who plays Jang Hak-su says about film: “At first, I thought it would be another war movie, but upon reading the script, I realized it’s more of a suspense thriller. I decided to take part because it sheds critical light on the sacrifices made by the intelligence unit and people of Incheon.”John H. Lee, who directed another Korean War film five years ago, said he’d been wanting to shoot another war movie since 71: Into the Fire, a story of South Korean students who fought in the Korean War: “I remember thinking after 71: Into the Fire that I wanted to film another war movie, the reason being the unique charm and drama of war films. They capture humanity in its direst situations.”
