The brand new official trailer for director Adam Wingard’s new A24 movie Onslaught arrived this morning, with the upcoming film set in the same world as Wingard’s The Guest.

Onslaught is set in the very same town as The Guest, with both films centering on the very same secret program. “So you could actually technically call this a sequel,” Wingard teases.

But will Dan Stevens make an appearance in Onslaught? Yes, actually. The star of The Guest is reteaming with Wingard for Onslaught, but he will NOT be playing the same character.

Instead, Dan Stevens is playing a mad German scientist in Onslaught, presumably the man responsible for creating the film’s “perfect soldiers” gone wrong. Stevens is actually glimpsed in today’s trailer, but he’s completely unrecognizable and buried under heavy prosthetics.

Dan Stevens played David Collins in The Guest, you may recall, a military test subject who becomes an unstoppable super soldier. He’s clearly not playing the same character in Onslaught, but the role of “German Scientist” looks to be a fun wink to his role in The Guest.

Watch the new trailer below for a sneak peek at Dan Stevens as German Scientist!

Adam Wingard’s Onslaught releases in theaters September 4, 2026.

The duo behind The Guest, director Adam Wingard and writer Simon Barrett, are re-teaming for the upcoming Onslaught, which stars Adria Arjona in the leading role.

Here’s the synopsis: “When a rogue squad of genetically engineered super soldiers break loose in the desert, a badass Army sniper must unleash hell to protect her young daughter.”
