When the first trailer for Adam Wingard‘s Onslaught dropped, it looked like exactly what the title promised: a relentless barrage of action, horror, and violence that almost felt like a long-lost cousin to The Terminator.
As it turns out, Michael Biehn had a similar reaction long before cameras ever rolled.
Speaking with Daily Dead, the Terminator and Aliens star said reading the screenplay was “about as close to The Terminator as anything I’d ever read before,” praising it for its “very strong, unstoppable” antagonist and calling it “an action horror movie with space for actors to work.”
Biehn admitted he wasn’t initially familiar with Wingard’s work, but said the filmmaker reached out personally, sharing how much Aliens had influenced him. The two have since become friends, something Biehn says has made the experience even more rewarding.
After seeing the finished film, however, Biehn’s excitement only grew.
He told Daily Dead that Onslaught is “without a doubt, the best movie I’ve been in since Aliens,” adding that while classics like The Terminator, Aliens, and Tombstone have already cemented his legacy, he’s thrilled to be part of what Wingard has created.
Biehn also reserved special praise for co-star Dan Stevens, calling him “the best actor I’ve ever worked with, except I worked with George C. Scott,” before adding that Stevens is “unrecognizably brilliant” in the film. He also singled out Adria Arjona, calling her “just dynamite,” and said the entire cast delivers.
If that wasn’t enough, Biehn believes audiences should prepare themselves.
According to the actor, Onslaught is going to “blow the doors off of any expectations,” describing it as “pedal-to-the-metal, action, horror, violence” with a punk rock ” ‘If you don’t like it, we don’t care’ vibe.” He added that the film moves at a blistering pace, calling it “very, very exciting” and “fast and furious.”
Based on the trailer, it’s hard to argue with the assessment. Onslaught looks like Wingard completely unleashed, embracing maximalist action and horror in a way that feels increasingly rare for a studio release.
Onslaught stars Adria Arjona, Dan Stevens, Michael Biehn, Drew Starkey, Regina Hall, Rebecca Hall, and Alex Pereira, and arrives in theaters September 4, 2026.
