> Kim Hyun-joo is back on the big screen after 15 years in Yeon Sang-ho's psychological thriller 'Silnakwon', which opens in Korean theaters on October 21.

## Key points

1. Kim plays a mother clinging to an AI version of her missing son.
2. Bae Hyun-sung plays her real son, who returns to her life.
3. It is her fourth project with director Yeon Sang-ho.

Actress Kim Hyun-joo has returned to the big screen for the first time in 15 years with 'Silnakwon', a psychological thriller from director Yeon Sang-ho. The film opens in Korean theaters on October 21, 2026.

In the film, Kim plays So-young, a mother who has been living inside a virtual reality built around an AI recreation of her missing son. Her life changes when her real son, Sunoo, played by Bae Hyun-sung, returns.

## Who does Kim play in Silnakwon?

Kim plays So-young, a woman who has been living a kind of artificial life. In an interview held in Seoul on October 16, she said she sees So-young as someone who has effectively been "dead while alive," building a perfect life through the AI son. A sudden reunion with a real son who feels like a stranger is, in her words, an unsettling and strange emotional experience.

## Why was the role hard to play?

Kim said she found it difficult to portray a grieving mother because she has not experienced motherhood herself. Instead of focusing on parental sorrow, she concentrated on a broader sense of loss, asking whether the longing is for a person or for the time and self that came with them.

## How does the film explore obsession?

Kim said she wanted So-young's emptiness to show in her eyes, even in ordinary morning scenes. Even after her real son returns, So-young cannot let go of the AI son, and Kim described that attachment as close to addiction, which she felt was necessary to make the character's choices believable.

## Her work with Yeon Sang-ho

This is Kim's fourth collaboration with Yeon, following the Netflix series 'Hellbound' (2021, 2024), the film 'Jung_E' (2023), and the series 'Sunsan' (2024). She said Yeon trusts actors and gives them space to play, and that he wanted to see how she interpreted his script.

## For international fans

Yeon Sang-ho is known internationally for the zombie film 'Train to Busan' (2016) and the Netflix series 'Hellbound'. Kim is recognized for her roles in both film and television. Information about overseas release dates or subtitles for 'Silnakwon' was not included in the source report, so check local distributors for availability.
