Onslaught violence gore MPA rating Adam Wingard

Get ready for a ride. Directed by Adam Wingard, who has carved out a reputation for intensely visceral filmmaking, the new action horror thriller Onslaught is set to explode onto the big screen on September 4th.

Hailing from the successful formula of cult classics like The Guest and You’re Next, this film promises to deliver a truly gonzo experience. It blends high-octane action with thrilling horror elements, setting the stage for an adrenaline-fueled cinematic event.

Onslaught has already garnered attention, and after reviewing the trailer, the Motion Picture Association ratings board has given the film a rating that signals exactly what viewers can expect: R for strong bloody violence, some gore, sexual material/nudity, and language.

The Crew Behind the Chaos

The film is anchored by a stellar ensemble cast. Adria Arjona stars as a mother navigating extraordinary peril, supported by a formidable group of seasoned actors including Dan Stevens, Drew Starkey, Michael Biehn, Reginald VelJohnson, and Rebecca Hall.

Adding an extra layer of physical prowess to the narrative is UFC Light Heavyweight Champion Alex “Poatan” Pereira. Known for his mastery of anaconda chokes and roundhouse kicks, Pereira brings a unique set of combat skills to the film, intensifying the stakes as the characters battle against otherworldly threats.

A Mother’s Fight for Survival

At its heart, Onslaught delivers a gripping narrative focused on desperate survival. The story centers on Arjona’s character, a mother living in a trailer park, who must rely on sheer grit and acquired skills to protect her loved ones. When a threat escapes from a secret military base, she finds herself facing the consequences of chaos.

The official synopsis reveals the escalating danger: when a rogue squad of genetically engineered super soldiers breaks loose in the desert, an Army sniper must unleash hell to safeguard her young daughter. This high-stakes scenario is woven through the film as various characters—including a German scientist, elite mercenaries, and community members—attempt to contain the explosive threat.

The screenplay was penned by Simon Barrett, who shares a history of collaborative work with Wingard on projects like The Guest and Godzilla x Kong: The New Empire, lending an assured, high-impact sensibility to the script.

Financially, Onslaught is a joint venture between Lyrical Media and A24, with A24 handling worldwide distribution. The film is produced under the Ryder Picture Company banner, ensuring a pedigree of cinematic quality as this chaotic spectacle prepares for release.
