A Familiar Collaboration in a New Genre
Adam Wingard and Simon Barrett reunite for Onslaught after previously collaborating on the 2014 thriller The Guest. This marks Wingard’s latest project following his work in the monster film space, now pivoting to an action-horror hybrid that emphasizes combat and survival over supernatural spectacle. The film was announced by The Hollywood Reporter in September 2024, with Wingard attached to direct from the start. Production took place in Albuquerque, New Mexico.
The Plot: Mother vs. Super Soldiers
According to the film’s official description, Onslaught follows Adria Arjona as a character living in a trailer park who must defend her family from an unstoppable threat. The antagonists—rogue super soldiers who have escaped a secret military installation—drive the film’s core tension. Early reports describe the film as a “gonzo action-horror” effort, suggesting a bold, high-octane approach to the genre hybrid. The trailer, which premiered in theaters before Backrooms, has already drawn significant attention from genre fans for its ambitious visual style and action sequences.

A24’s September Release Strategy
Onslaught lands in theaters on September 4, 2026, positioning it as an early fall genre release for A24. The studio has built a strong reputation for backing independent and unconventional action and horror projects. Wingard’s previous success with mainstream audiences means this film carries mainstream distribution expectations while retaining the creative freedom A24 is known for supporting. The early trailer debut suggests the studio is confident in the project’s appeal and is beginning its promotional push months in advance.
