The Message (2009)

Both take place during the Japanese Colonial era and involve the questioning of suspects for anti-Japanese motives - espionage films. One takes place in a mansion house and the other takes place in an isolated hotel. In both films, the Japanese are trying to hunt down a mole called "Phantom". These similarities are because both films are adapted from Mai Jia's 2007 novel, The Message.
