What’s the Deal With Onslaught?
Here’s the tea: Adria Arjona plays a mom living in a desert trailer park who also happens to be a former army sniper. When something dangerous escapes from a secret military base, she’s the only one who can save her family. Cue the adrenaline, the action, the explosions, and probably some really sick fight scenes.
While she’s doing her best action-hero-mom thing, mercenaries are scrambling to contain the threat, and yeah, things get completely out of hand. Think “super soldier gone wrong” meets “underdog mom who will destroy anyone threatening her kids.” It’s the kind of setup that sounds wild but somehow works perfectly.
The Cast Is Actually Stacked (And That’s An Understatement)
Let’s talk about the lineup, because holy moly:
- Adria Arjona (Andor, Hit Man) as the lead sniper mom
- Rebecca Hall (Godzilla vs. Kong, The Night House) in a supporting role
- Dan Stevens (The Guest, Cuckoo) as a German scientist involved in some shady experiments
- Alex Pereira (UFC champion) as “The Butcher,” the villain who brings anaconda chokes and roundhouse kicks to the fight
- Michael Biehn (Aliens, The Terminator) and Reginald VelJohnson (Die Hard)—yes, those legends are in this
- Drew Starkey (Queer) is rounding out the ensemble

Dan Stevens reuniting with director Adam Wingard is extra exciting because they previously made The Guest, a cult-favorite action thriller everyone loves. And Alex Pereira playing a villain called “The Butcher” sounds like the most fun thing ever. UFC champion entering the movie world? We’re here for it.
Why This Movie Is Actually a Big Deal
A24 has this killer track record of making original films that punch way above their weight. Remember Everything Everywhere All at Once? Midsommar? Uncut Gems? Moonlight? That’s the studio behind Onslaught.
The Fox News preview literally calls it “a shot of adrenaline to the chest” and says it has similar energy to Civil War, another A24 hit. And honestly, after years of superhero slop and the 13th installment of some franchise we didn’t ask for, we need this. If a studio makes something even partially original, people care—and that’s exactly what’s happening here.
Meet the Director: Adam Wingard, the Scream King
Adam Wingard isn’t just any director. This guy’s basically a genre master. His filmography includes:
- The Guest (2014): That cult action thriller with Dan Stevens that developed a massive following
- Cuckoo (2024): Horror film (yeah, Dan Stevens and Wingard are co-stars again)
- Godzilla vs. Kong (2021): Proof he can handle massive blockbuster budgets
One reviewer said The Guest felt like “Halloween as an action movie,” but Onslaught feels more like “a Jason Voorhees action movie”—which means it’s leaning harder into the horror side of things.
The movie was shot in New Mexico, and Wingard posted on Instagram in November 2024 that “Week 1 in the can” with an awesome cast and crew. Fun fact: some scenes were filmed but later cut because they could have made the movie “a convoluted mess”.
When Can You Watch It?
Mark it down: September 4, 2026. That’s when Onslaught hits theaters nationwide, distributed by A24. The trailer dropped on June 2, 2026 (literally today), and it premiered in theaters ahead of Backrooms.
