From acclaimed Korean filmmaker Kim Jee-woon (The Good, the Bad, the Weird, I Saw the Devil) comes this historical crime thriller about a police officer working for the Japanese, who secretly switches sides and begins working with the resistance he is supposed to help bring down. Featuring a large cast of characters, it can be a bit difficult to keep track who's who and on which side. However, the core relationship of the film is the growing friendship between Lee Jung-chool and Kim Woo-jin, despite the fact that both are supposed to be on opposite sides.
With The Age of Shadows, Kim Jee-woon takes a page out of Korea's dark history and creates a pretty decent crime thriller, which includes some elements of an espionage film. Even though it takes a while to figure out where all the major players stand, The Age of Shadows is quite well constructed, particularly a lengthy set-piece aboard a train. It should be noted that there are some torture scenes late in the film, which can be quite hard to watch, however it's not enough to dissuade me from recommending The Age of Shadows.
