02 / Facts & trivia about Onslaught
- 01
Same universe as The Guest
In July 2026, Wingard confirmed Onslaught shares continuity with The Guest (2014): David Collins was part of the same secret organization, and in the director's mind, You're Next completes the trilogy.
- 02
The villain has a real name
Dr. Hans Kammler borrows his name from an SS general who ran the Reich's secret projects. Dan Stevens' poster reads: “The government buries its mistakes. He resurrects them.”
- 03
A UFC champion as the executioner
Alex Pereira, two-time MMA world champion, plays The Butcher in his biggest film role yet. The poster warns: “He escaped, and you're on the cut list.”
- 04
Michael Biehn is back
The Terminator and Aliens icon returns to blockbusters as Baylor. A24 didn't miss the joke: “His deal is about to be terminated.”
- 05
92 minutes, no fat
Shot in Albuquerque, New Mexico between November 2024 and January 2025, the film is lean and earned a rare IMAX push from A24 for a genre title.
- 06
1980s video-store era
The official campaign runs on retro rental-store posters; the studio calls the film “gonzo action horror”. The press summed up the trailer: Wolfenstein meets Terminator meets Friday the 13th.
