Meaning, we may get the full trailer in 30 days. Count us intrigued.

An On-the-Run Thriller Inside a Haunted Attraction

Written and directed by Saulnier, the feature transforms a seasonal haunt into the backdrop for a relentless, high-stakes narrative. Slayground takes its name from the fictional immersive haunted house where the lead character works. The plot centers on a fugitive played by Cory Michael Smith. He becomes the prime suspect in a high-profile mass murder investigation. However, after making a desperate escape from law enforcement custody, he flees into the night to evade a massive, multi-agency search. As he scrambles to dodge authorities and clear his name, the attraction’s terrifying maze becomes a central pressure cooker for the narrative.

A Powerhouse Ensemble Ensemble Cast

To bring the pulse-pounding thriller to life, Saulnier has assembled a stacked ensemble cast. The lineup features Imogen Poots (Green Room), James Badge Dale (The Empty Man), Matty Matheson (The Bear), and Cory Michael Smith (Saturday Night). Chase Sui Wonders (I Know What You Did Last Summer) also joins the cast, alongside Sophie Wilde (Talk to Me), Young Mazino (The Last of Us), and Stephen Root (Widow’s Bay).

The Digital Countdown Begins

While A24 has not yet announced a formal theatrical release date for Slayground, the viral site is already active. Stay tuned; something is happening in 30 days.
