Adam Wingard’s ‘Onslaught’ Trailer Unleashes Brutal First Look at Adria Arjona, Dan Stevens and Alex Pereira in High-Stakes Chaos

A24 has released the first trailer for Onslaught, the upcoming action-thriller directed by Adam Wingard and written by Simon Barrett. The film is set to arrive in theaters this fall and is already getting attention for its intense action and violent premise.

The story follows a woman played by Adria Arjona, who is trying to live a quiet life as a single mother. That peace does not last long. Her past catches up with her when a dangerous group of genetically engineered super soldiers begins hunting her and her daughter. The twist is that her character is not just an ordinary parent. She is also a former sniper, which means she knows exactly how to fight back when things get deadly.

The trailer shows a world filled with high-speed action, brutal fights, and a constant sense of danger. The super soldiers are not normal enemies. They are enhanced, aggressive, and built for destruction. That raises the stakes for Arjona’s character, who is forced to rely on both her military skills and her instincts as a mother to survive.

Adam Wingard and Simon Barrett are known for working together on films like You’re Next, The Guest, and Blair Witch. According to the report, Onslaught feels like a return to their earlier style, with a gritty, pulpy tone and a strong 1980s-inspired feel. The trailer also highlights the director’s focus on fast pacing and practical intensity rather than slow buildup.

Dan Stevens appears in a key role, adding a strange and unpredictable energy to the story. His character is shown in the trailer with an unusual performance style that fits the film’s chaotic tone. The cast also includes professional fighter Alex Pereira, who plays one of the super soldiers, along with Michael Biehn, Drew Starkey, Eric Wareheim, Maurice Greene, and Reginald VelJohnson.

The report notes that Wingard has recently worked on big studio films like Godzilla vs. Kong and Godzilla x Kong: The New Empire. Onslaught, however, feels like a return to smaller, more intense genre filmmaking, closer to his earlier projects. The tone is described as violent, fast-moving, and unapologetically over-the-top.

One of the standout elements in the trailer is the design of the super soldiers. Their glowing eyes and controlled movements give them a disturbing presence, making them feel less human and more like weapons. Combined with nonstop action sequences, the trailer suggests a film that does not slow down once it begins.

A24 continues to build its lineup of genre films this year, and Onslaught is one of its most aggressive entries so far. The studio is also preparing several other releases, but the report suggests that this film stands out for its raw energy and action-heavy style.

The film is scheduled to hit theaters on September 4. Based on the trailer reaction, Onslaught is shaping up to be one of A24’s most intense releases of the year, driven by survival stakes, personal trauma, and nonstop combat against overwhelming forces.
