Adam Wingard’s “Onslaught” Trailer Introduces New Supersoldier Villains Ahead of September Release

The first official trailer for the upcoming action-horror film *Onslaught* showcases a rogue gang of genetically engineered supersoldiers. It highlights Adria Arjona’s Army sniper protecting her young daughter from the threat. Dan Stevens appears as a German mad-scientist who names his creations—Crybaby, Cockroach and the Butcher, the latter portrayed by UFC champion Alex Pereira wielding a meat cleaver. The visual style leans heavily on retro genre aesthetics.

Director Adam Wingard, known for *Godzilla* entries, *You’re Next* and *The Guest*, explained at the San Diego Comic-Con that John Carpenter’s work shaped the film’s tone, citing the original *Assault on Precinct 13* as the “biggest influence.” Wingard told reporters that Carpenter’s “magic” and the tension of *Assault on Precinct 13* guided his approach to the film’s action-horror balance, adding that the new trailer “captures the gritty, relentless energy” he aimed to deliver.
