Director Kim Mi-jo's 'Gyeongju Pilgrimage' is a film that tells the story of a family who kidnaps a murderer to seek revenge. The director raises questions about whether forgiveness solves everything and intends to convey the message that viewers can choose for themselves through private retribution. The film incorporates the family's everyday life and humor revealed during the revenge process, blending diverse genres. Lee Jung-eun, who played the role of Ok-sil, the mother character, completed in-depth acting by referring to the records of Sewol ferry victims' families and the psychology of crime victims with director Kim. The three sisters in the film were created based on the motif of director Kim's four-sister family, each with different personalities and thoughts, showing a realistic family relationship.
