Onslaught trailer unveils super‑soldier showdown in Adam Wingard’s new film
A24 released a new trailer for Adam Wingard’s upcoming action‑horror film Onslaught, which premiered at San Diego Comic‑Con. Wingard, who co‑writes the script with Simon Barrett, describes the movie as a spiritual sequel to his 2014 cult thriller The Guest, set in the same town.
The trailer follows former Army sniper Celeste (Adria Arjona) as she battles a rogue squad of genetically engineered super soldiers—identified as Crybaby, Cockroach and the Butcher—to protect her young daughter. The cast also includes Dan Stevens, Eric Wareheim, Reginald VelJohnson, Michael Biehn, Alex Pereira, Drew Starkey and Rebecca Hall. The film will open worldwide, including IMAX formats, on September 4, 2026.
The promotional material highlights intense gunfights, brutal combat and the film’s connection to Wingard’s earlier work, positioning Onslaught as a new entry in his gritty indie‑horror repertoire.
