A rumour about a superhero movie gives a struggling stunt school a sudden influx of customers in James Thoo’s Singaporean mockumentary The Sandbox. The joke has a poignant real-world counterpart: Sandbox Training Ground, the school that inspired the film, closed before its cinema release.

What happens in The Sandbox?
A stuntman, his best friend and the friend’s ex-wife are trying to keep their declining school alive. When word spreads that Marvel Studios might be scouting locally, wannabe superheroes and other hopefuls arrive expecting to train for a big break. The casting opportunity is a rumour within the film’s story, not a confirmed Marvel production.

The film had its world premiere at the 2025 Singapore International Film Festival. Shaw Theatres lists its Singapore cinema release for 8 October 2026.

4 Kheng said writer-director Thoo gave the performers considerable freedom to develop their individual characters. Azzhar plays Shafiq Hakim, described as a risk-averse perfectionist and former Ministry of Education employee. The available reporting does not establish how each member of the ensemble developed their role.

Why does the real school’s closure matter?
Sandbox Training Ground closed in September 2026, with high costs reported as a reason. Earlier reporting had also identified high rent and insufficient funding as threats to its survival.

9 That makes the film’s fight to keep a creative small business open more than a fictional setup. The Singapore International Film Festival describes the story as an allegory for challenges facing the country’s creative industries; the school’s closure gives that reading a concrete example.

What superheroes did the cast imagine?
CNA reports that Hartono, Oon and Kheng discussed the heroes Singapore might need, and its available excerpt names one imagined figure, Fan Man, also called Tan Jisu. The excerpt cuts off before explaining his power or identifying who proposed him. It does not provide enough detail to reliably attribute the other heroes, their powers or Hartono’s and Kheng’s personal superhero identities.
