Trivia, insights & behind the scenes
Choi Dong-hoon shot both Alienoid films back-to-back over 13 months, with Part 2's medieval sequences filmed before Part 1's release.
The film's Joseon-era alien conspiracy deliberately mirrors Korean anxieties about hidden powers controlling society—colonial occupation as literal body-snatching.
