Onslaught Fun Facts: Thanks To His Legendary Knockout Power, He Now Brings That Same Intimidating Presence To Hollywood

UFC Champion Alex Pereira’s Feature Acting Debut:
UFC Light Heavyweight Champion Alex Pereira is taking his talents from the octagon to the big screen. The Brazilian fighting superstar is set to make his acting debut as The Butcher in Onslaught, a menacing super-soldier built for destruction. Pereira, who built a terrifying reputation in mixed martial arts thanks to his bone-crushing kicks and legendary knockout power, now brings that same intimidating presence to Hollywood.

A Spiritual Successor to The Guest (2014):
Fans of director Adam Wingard and writer Simon Barrett have been eagerly awaiting a sequel to their 2014 cult-favorite thriller The Guest for over ten years. While their new project, Onslaught, isn't a direct sequel, it plunges right back into the world fans loved. The movie dives deep into the very same dark storyline: secret government programs running hidden facilities, turning ordinary soldiers into unstoppable, genetically modified human weapons.

Adria Arjona Pulled Double Duty:
Onslaught is shaping up to be a defining moment for Adria Arjona. She stars as a former Army sniper turned trailer-park mom who will stop at nothing to defend her young daughter from a squad of genetically modified super soldiers. Even bigger? Arjona isn't just bringing the action on screen; she’s also making moves behind the camera, serving as an executive producer on the film alongside movie studio powerhouse A24.

A High-Profile Godzilla x Kong Reunion:
Director Adam Wingard may be taking a break from directing Titan monster blockbusters like Godzilla x Kong: The New Empire to make a gritty, R-rated thriller, but he didn't leave his favorite actors behind. Wingard reunited with two of his biggest stars for his new Onslaught project: Rebecca Hall and Dan Stevens. For Stevens, this marks a special reunion; he previously starred in Wingard’s 2014 fan-favorite thriller The Guest. Now, both actors are joining the director as he steps away from Hollywood mega-franchises to return to his intense, independent-film roots.

An Iconic 80s & 90s Action/Sci-Fi Cast:
Adding extra firepower to Onslaught is a supporting cast packed with Hollywood royalty, featuring two legend-status action and sci-fi icons from the 1980s and '90s.

First up is Michael Biehn, unforgettable for his roles in classics like The Terminator and Aliens. He steps back into uniform as the cold-blooded leader of a ruthless mercenary team hired to track down and eliminate the escaped super-soldiers.

Joining him is action icon Reginald VelJohnson, best known for playing the beloved cop in Die Hard. Stepping into a fun new role, VelJohnson plays one of the quirky, colorful residents who calls the local trailer park home.

Onslaught Review: Packed With Practical Gore, Rapid-Fire Shootouts, And Adria Arjona Totally Kicking Ass

After spending years directing massive, blockbuster monster battles in the Godzilla vs. Kong franchise, director Adam Wingard and screenwriter Simon Barrett are returning to their roots. Teaming up with A24 for the film Onslaught, the duo who previously brought horror fans cult hits like You're Next and The Guest are stepping away from big-budget spectacles to deliver a gritty, mid-budget thriller. While Onslaught serves up a fun, blood-soaked splatter to classic action-horror, it ultimately falls short of delivering the relentless, heart-pounding terror its title suggests.

The story takes place in a quiet, remote corner of the New Mexico desert. Celeste (Adria Arjona), a former Army sniper who is living with PTSD and trying to stay under the radar. She spends her days working as a property manager at the trailer park, keeping to a quiet routine. However, her peaceful, secluded life is completely thrown off balance when her ex-husband suddenly shows up unannounced and drops off their young daughter, Daisy, on short notice.

Meanwhile, chaos is brewing nearby at a secret military research facility; an eccentric, delightfully unhinged scientist (Dan Stevens) has created a team of three virtually unstoppable super-soldiers. These genetically modified soldiers are led by a terrifying brute known as "The Butcher," played by former UFC champion Alex Pereira.

Before long, the dangerous trio breaks free from their handlers' control and descends upon the trailer park, fully loaded with heavy military weapons, cleavers, and chainsaws. Once they arrive, they begin an onslaught, and Celeste is forced to tap into her full military training and go into survival mode, taking on the deadly squad to protect her young daughter and her eccentric neighbors.

Adria Arjona as Celeste commands your attention on the big screen in Onslaught; instead of playing a typical, flat action hero, she brings real emotional depth to the role, balancing a tough-as-nails attitude with a deep, protective instinct for her daughter. She makes every single moment feel authentic; whether she's handling heavy weapons, taking physical hits, or executing precise combat moves, Arjona performs with a raw, believable intensity. Her powerful performance ultimately holds the entire movie together and keeps the audience hooked.

What elevates the movie Onslaught, beyond a standard survival action horror, is its colorful cast of eccentric supporting characters. Reginald VelJohnson steals scenes as a tough-as-nails, shotgun-wielding veteran living in the trailer park, a fun, nostalgic nod to his classic action roles.

Action veteran Michael Biehn, who plays Baylor, a U.S. government official sent to inspect the scientist's dangerous super-soldier program. Biehn's presence adds another fun layer of nostalgia for action movie lovers; having famously played iconic, battle-tested heroes in The Terminator and Aliens, his casting serves as a full circle moment in this film.

On the other side of the chaos, Drew Starkey plays a government agent tasked with cleaning up the mess. Together, these wildly entertaining performances give the onslaught siege a distinct fun vibe, filling the movie with campy humor and high-energy personality.

Wingard attempts to pull off a tricky balancing act here, blending the terrifying vibes of a classic slasher movie with the explosive energy of a high-concept action flick in Onslaught. Instead of building tension through a silent, towering killer stalking victims through the shadows with a cleaver and an axe, the movie relies on rapid gunfire.

In the movie Onslaught, the killer soldiers are armed with heavy assault rifles, and as a result, the big action sequences end up feeling more like a standard tactical military thriller than a genuinely terrifying horror film.

Onslaught works as a decently fun thriller that highlights Wingard’s signature talent for delivering sleek, stylish action. If you're looking for an entertaining movie night packed with practical gore, rapid-fire shootouts, and Adria Arjona totally kicking ass, there is plenty here to enjoy.

However, if you're going in expecting a nonstop, blood-pumping action-horror masterpiece, you might walk away feeling disappointed, as the film lacks the terrifying suspense that keeps the audience on the edge of their seats.
