At Busan, one short film turned a surreal subway commute into a sharp statement about work, isolation, and the future of screen production. Worm Train also became one of the clearest examples yet of how directors are using Kling AI not to replace filmmaking, but to expand what TV & video storytelling can do.
Screened at the Asian Contents & Film Market during the 31st Busan International Film Festival, Worm Train comes from acclaimed South Korean filmmaker Sung-Soo Kim. Inspired by Franz Kafka’s The Metamorphosis, the film imagines an overworked commuter transformed into a giant worm who still has to endure a crowded subway ride and make it to work. The absurd premise lands as social commentary, exposing the emotional numbness and dehumanizing routines of modern life.
But beyond its premise, Worm Train matters because of how it was made. The project became a focal point in a larger conversation around AI filmmaking, hybrid production pipelines, and what cinematic authorship looks like in an era of rapidly evolving creative tools.
Why Worm Train Stood Out at Busan
The central image in Worm Train is unforgettable: a giant worm being jostled inside a packed subway car while most passengers barely react. That strange, deadpan tension gives the film both visual power and thematic bite. Rather than using AI for spectacle alone, the filmmakers used it to serve tone, metaphor, and directorial intent.
Kim reportedly began the project earlier in the year but paused when available tools could not convincingly handle the physical complexity of the subway sequence. The challenge was not simply generating a creature; it was choreographing believable movement, collisions, reactions, and continuity in a cramped public setting. Once Kling 4.0 improved motion continuity, scene control, and shot progression, production resumed.
That detail is significant for anyone following TV & video innovation. It shows that AI-assisted production is increasingly judged by the same standards as traditional filmmaking:
- Can it maintain visual continuity?
- Can it execute a director’s blocking and pacing?
- Can it support performance, tone, and story?
- Can it integrate into a professional production workflow?
In the case of Worm Train, the answer appears to be yes.
Kling AI and the Rise of the Hybrid Filmmaking Workflow
A major takeaway from the Busan panel was that AI works best when it is directed, not merely prompted. That philosophy sits at the heart of Worm Train and the other projects discussed alongside it.
Rather than framing AI as an all-in-one replacement for crews and craft, the filmmakers described a hybrid model. Traditional directing, planning, cinematics, and specialist collaboration still shape the final work, while AI tools help execute difficult, expensive, or visually ambitious sequences.
What Kling AI brought to the process
Across the panel, creators highlighted features that are becoming increasingly useful in TV & video production, including:
- Continuous motion generation between frames
- Improved control over character movement
- Better scene transitions and shot development
- Keyframe-based control points for story beats
- High-resolution output suited for large-scale visuals
For Worm Train, that meant the difference between a stalled experiment and a finished cinematic short. Kim’s broader point was equally important: technology can generate images, but human creators still give those images meaning.
What Other Directors Revealed Beyond Worm Train
The Busan discussion went well beyond one film, offering a snapshot of how AI is entering multiple corners of the screen industry.
AI in microdrama and virtual performance
Sang Wook Lee, who now leads MBC C&I’s AI division, presented Rendering Love, a microdrama series developed with Barunson E&A. The romantic comedy follows a virtual idol group and a fan who can see through their hidden identities. Its production model mirrored its theme: live action represented the real world, while AI generated the group’s stage performances.
This blended approach is especially relevant to TV & video formats where budgets, episode lengths, and audience expectations demand speed without sacrificing visual identity.
Using AI for scale in period storytelling
Director Harry Hyun discussed Natasha, a period romance thriller inspired by a Baek Seok poem. Here, the production preserved live action for emotionally nuanced scenes while using AI to create costly environments such as a 1940s snowstorm and crowd-heavy sequences.
That may be one of the most practical uses of AI in narrative production today: protecting performance-driven scenes while lowering the cost of scale.
Animation’s new advantage
Veteran Chinese animator Wei Li explained how AI can also transform long-form animation. On Born of the Tides, a 105-minute feature with more than 2,350 shots and 200 characters, AI reportedly reduced the cost of experimentation and helped realize complex wide shots that would have been difficult to maintain at big-screen quality in the past.
For studios and independents alike, that opens a meaningful door. Niche stories that once struggled to justify their production demands may now become more feasible.
What Worm Train Says About the Future of TV & Video
The bigger lesson from Worm Train is not that AI is taking over filmmaking. It is that the technology is becoming increasingly directable. That distinction matters.
For creators in TV & video, the most promising path forward seems to be:
- Start with a strong directorial vision
- Use AI selectively where it adds scale, efficiency, or visual possibility
- Keep human performance, editing judgment, and story design at the center
- Build workflows where artists and tools complement each other
If this model holds, the phrase “AI film” may eventually become less important than the finished work itself. Audiences care about whether a story is compelling, emotional, and visually coherent. They do not reward technology for its own sake.

Conclusion: Worm Train Is a Sign of Where Screen Storytelling Is Headed
Worm Train is memorable because it pairs a haunting concept with a practical demonstration of how AI can fit into modern filmmaking. At Busan, the message from directors was remarkably consistent: cinematic value still comes from human judgment, taste, and storytelling. The tools are changing fast, but authorship remains the anchor.
For anyone watching the future of TV & video, Worm Train is more than a standout short. It is a case study in how AI can be folded into serious creative work without losing the voice of the filmmaker. The technology may evolve, but great cinema will still depend on the people shaping it.
