Heartbeat by Lee Chang-dong: November 2 Release and Cast

The film found under the search term ‘Heartbeat Lee Chang-dong’ will be released on Netflix on November 2, 2026. It is director Lee Chang-dong’s first short film. This marks the worldwide streaming release of the film shown at festivals in 2022.

The release schedule is based on Netflix’s announcement dated October 30, 2026.

Release schedule and basic film information

The release platform is Netflix, and the announcement does not specify an exact release time. Festival records list the film’s year as 2022. The runtime follows the San Sebastián International Film Festival’s record from that year.

The schedule is confirmed in the Netflix release announcement. The runtime and original language are listed in the San Sebastián International Film Festival’s film record.

The difference between the 2022 premiere and the 2026 release

The 2026 date marks the start of the existing short film’s availability on Netflix. The Jeonju International Film Festival presented the film as a world premiere in 2022. The retrospective at the time was titled ‘Lee Chang-dong: The Truth of the Invisible’.

Changing the film’s year to 2026 would therefore obscure its premiere history. Film information should list 2022, with the streaming availability date noted separately. The festival history can be checked in the Jeonju International Film Festival’s retrospective announcement.

Heartbeat cast and roles

Kim Gun-woo plays the lead character, Cheol, and Jeon Do-yeon plays his mother. Sul Kyung-gu provides the voice of his father. Below are the main roles announced by Netflix.

The types of participation follow the role descriptions in Netflix’s announcement.

Plot summary without the ending

The story centers on eight-year-old Cheol, who worries about his mother. His mother has depression. Worried about her being home alone, Cheol runs home during class.

This summary is based on the San Sebastián International Film Festival’s official synopsis. The child’s anxiety sets the events in motion. The major scenes that follow and the ending are not covered here.

What to watch for

One point to watch is how the camera follows Cheol’s face. Netflix explains that the film follows the boy’s face from beginning to end. With this in mind, viewers can focus on the changes in his expressions.

• The character’s perspective: Notice what the child sees and reacts to as he worries about his mother.
• The performance: Consider both the dialogue explaining the situation and the emotions shown on his face.
• The production’s starting point: According to Netflix’s announcement, WHO and BCAF proposed making the film on the subject of depression.

These viewing suggestions are based on Netflix’s introduction to the film. They are not an assessment based on having watched it. A short runtime need not be taken to mean light subject matter.

How to watch and a comparison of viewing options

Netflix is the viewing option announced for Korea this time. Past festival screening records do not indicate screenings that can currently be booked. The confirmed schedule and items requiring separate checks are as follows.

The difference between subtitle support and dubbing

The language support confirmed in this announcement is subtitles. The listed languages are English, Spanish, Portuguese, Chinese, French, and German. The announcement does not list dubbing languages.
