A24 Just Dropped a Terrifying First Trailer for Jeremy Saulnier’s Next Movie ‘Slayground'

Jeremy Saulnier has built a reputation as one of the most reliably tense filmmakers working today, with ‘Green Room’ and ‘Rebel Ridge’ both showcasing his knack for turning ordinary people into desperate survivors. His next project has been shrouded in mystery for months, cycling through vague details and a placeholder title that gave almost nothing away about what audiences should actually expect.

That mystery started clearing up this week. A24 quietly surprised audiences at theatrical screenings of ‘Resident Evil’ with a teaser for the film, now officially retitled ‘Slayground‘ after previously being known simply as ‘October.’

The story follows Cory Michael Smith as the primary suspect in a mass murder investigation who escapes police custody and goes on the run to prove his innocence while a massive manhunt closes in around him. Much of that chase reportedly unfolds around the haunted attraction referenced in the title, a setting where the film’s marketing has cleverly blurred the line between staged scares and something far more real.

That setting also explains the retitle. According to reporting on the production, the shift away from “October” happened once A24 decided it did not want to wait until that month to release the film, a scheduling change that made the original title feel disconnected from the eventual release plan. “Slayground,” tied directly to the haunted attraction at the center of the story, ended up being both a better fit and a sharper marketing hook.

The ensemble cast rounds out with Chase Sui Wonders, Sophie Wilde, Young Mazino, and Stephen Root, alongside Imogen Poots, James Badge Dale, and Matty Matheson. That lineup gives Saulnier a mix of rising stars and reliable character actors, a combination that has worked well for him in past projects built around small groups of people trying to survive an escalating nightmare.

Adding to the anticipation is the film’s score, reportedly composed by Trent Reznor and Atticus Ross, the Oscar-winning duo behind acclaimed scores for David Fincher and Luca Guadagnino projects, including their landmark work on ‘The Social Network.’ Their involvement alone has generated significant excitement among genre fans, given how well their signature tension-building style tends to pair with exactly the kind of stripped-down, high-stakes filmmaking Saulnier is known for.

A24’s marketing rollout has leaned heavily into mystery, launching a “Run Like Hell” campaign complete with a countdown clock on the film’s official website and cryptic messaging that mirrors the haunted-house aesthetic of the story itself. The studio has not confirmed an exact release date, though the teaser reportedly ends on the word “Fall,” and internal screenings have suggested a runtime of roughly two and a half hours.

Whether A24 manages to get ‘Slayground’ into theaters before the end of the year remains an open question, especially given how recently the marketing campaign kicked off. Either way, pairing Saulnier’s tightly wound sensibilities with a premise this immediately unsettling has fans paying close attention to whatever A24 reveals next.
