Quicksand is about to become a whole lot more terrifying.

One of the genre highlights making its World Premiere at Fantastic Fest 2026 is The Swallow, a new creature feature from filmmakers Kevin Kölsch and Dennis Widmyer, the duo behind Starry Eyes and the 2019 remake of Pet Sematary.

The filmmakers are putting a nasty spin on one of horror’s classic hazards, turning quicksand into a sentient, flesh-hungry threat.

Stranger Things star Grace Van Dien leads the cast, with Jack Wright (A Bloody Night), Tayler Buck (Annabelle: Creation), Kalama Epstein (The Fabelmans), and Kayla DiVenere (Love, Victor) also starring.

The official synopsis promises a lean, effects-heavy nightmare:

“A sentient, quicksand-like sludge terrorizes a group of young people in this brutally efficient, effects-forward creature feature.”

Yeah, suddenly getting stuck in the mud doesn’t sound so harmless.

Kölsch and Widmyer say The Swallow is a return to the kind of horror that originally pulled them toward the genre.

“The Swallow is a tonal throwback to the type of horror that made us excited about this genre in the first place,” the filmmakers said. “Something pure, visceral and absolutely harrowing. Our hope is that it will make you never look at the ground the same way again.”

The film is produced by James Harris and Mark Lane for Tea Shop Productions, John Finemore for Lost City, Adam Goldworm for Aperture Entertainment, and Josh Goldbloom, with Kölsch and Widmyer also producing. James Hoppe serves as executive producer.

The Swallow will make its World Premiere at Fantastic Fest, which returns for its 21st edition from September 17-24, 2026.

With a sentient sludge creature waiting beneath the surface, this one might make you think twice before stepping anywhere near the ground.
