Phantom

Both are thrillers set in 1930s Korea that include LGBTQ main characters and a lot of the plot happening in an isolated location. imho 'Phantom' is more of an action thriller, while 'The Handmaiden' is more of a psychological thriller.

Both are historical action film set in the Japanese occupation era in Korea. Both are film about how the Koreans fight the Japanese

both movie has north Korea setup
bit of spy element
bulk of expectation from everywhere wheter it is family or party

Same director and writer with Park So Dam appearing in both films. Both are set during the Japanese colonialism in Korea and have strong female characters. The Silenced is set in a boarding school while Phantom is set in an isolated hotel. The Phantom is an action thriller espionage film while The Silenced is a horror mystery film. LGBT-coded characters in both films. Both show violence towards Koreans and the horrors of Japanese colonialism during the Japanese colonial period in Korea.

These are my two favorite adaptations of the novel! 'The Message' is a thriller full of unreliable narrators while 'Phantom' is much more of an action movie, but both have excellent chemistry between their female leads and a satisfying story.
