Hong Kong’s Cappu Films Boards Sci-Fi Action Thriller ‘Overstake,’ Blending Live-Action Shoot with Generative AI

Hong Kong-based sales and distribution banner Cappu Films has boarded the international rights for “Overstake,” an ambitious sci-fi action thriller directed and written by filmmaker Stas Mareev. The project represents a striking fusion of traditional filmmaking and cutting-edge technology, pairing a gritty live-action principal photography shoot with industrial and urban settings that are entirely rebuilt and reimagined through generative artificial intelligence.

Cappu Films is officially introducing the high-concept genre title to international buyers, distributors, and industry executives at the ongoing Asian Contents & Film Market, held in conjunction with the prestigious Busan International Film Festival in South Korea. The market serves as a major hub for film financing, acquisitions, and cross-cultural cinematic partnerships within the Asia-Pacific region and beyond, making it the ideal launchpad for a film pushing technological boundaries.

The narrative of “Overstake” plunges audiences into a relentless, high-stakes gauntlet. The story follows a wounded veteran who finds himself thrust into a deadly, blood-soaked betting game for a life-changing financial payout. His mission is deceptively simple in premise yet impossibly difficult in execution: he has a strict two-hour window to traverse a sprawling, hostile industrial city while keeping his ex-wife alive. Complicating matters further, everyday strangers wandering the city receive real-time offers and prompts on their mobile phones, incentivizing them to either assist the protagonist or actively hunt him down and stop him in his tracks. Behind the scenes, the shadowy organizers of this lethal competition broadcast the man and his former wife’s harrowing fight for survival to an unseen, bloodthirsty audience, turning human suffering into a spectator sport.

The ensemble cast supporting this gritty sci-fi premise features a slate of recognized actors, including Konstantin Adaev, Vika Tokareva, Oleg Chernov, Konstantin Sidikhin, Denis Starkov, and Sergey Russkin, who bring dramatic weight to the physical and emotional crucible of the film.

For writer-director Stas Mareev, “Overstake” is not merely a new project, but a rare creative opportunity to revisit a cinematic vision he has previously explored. Commenting on the unique production methodology, Mareev noted that the feature offers a chance to return to a film he had already directed and effectively rebuild its entire world at a scale that was previously impossible for his production team due to traditional budget and resource limitations. He emphasized that the human core elements—specifically the dramatic performances and the foundational story—remain the absolute bedrock of the production. Meanwhile, the integration of generative AI allows him to profoundly rethink the surrounding environments, heighten the action sequences, and refine the visual language of the movie without ever sacrificing its emotional resonance or character-driven heart.

Industry response to the project’s early materials has been strong, driven by the combination of a high-concept sci-fi premise and novel technological execution. Janice Woo of Cappu Films spoke enthusiastically about the acquisition, noting that the sales company has successfully managed international sales for a wide variety of titles within this sector, with science fiction and action remaining particular core strengths for the company’s catalog. Woo shared that the team was immediately impressed by Stas Mareev’s promotional footage and look forward to formally introducing the film to their extensive network of distribution partners attending the market in Busan.

Because the groundbreaking generative AI post-production and world-building work is still actively in progress, international buyers and distributors attending the Busan market will not yet be treated to a completed cut. Instead, Cappu Films is presenting a dynamic promotional package accompanied by a select handful of fully finished sequences to demonstrate the unique visual aesthetic and tone of the hybrid production.

“Overstake” anchors a diverse and robust sales slate that Cappu Films is bringing to the Busan International Film Festival this year. Alongside Mareev’s sci-fi thriller, the company’s market lineup features a wide range of genres and formats from international filmmakers. These include “Banr”; “Fox Hunt”; “Ephemera,” the acclaimed Tribeca Film Festival selection directed by Shan Jiang; “Operation Doolittle,” an expansive World War II spy series told across nine immersive episodes; the martial arts action film “Lion Fist”; Joy Hopwood’s heartfelt Australian dramedy “Her Last Laugh”; and “Zombie Plane,” a comedic action romp toplined by an eclectic cast featuring Vanilla Ice, Sophie Monk, and action legend Chuck Norris.
