Watch Adria Arjona, Dan Stevens. Michael Biehn and more in the trailer for Adam Wingard’s Onslaught

Onslaught is the new action horror film directed by Adam Wingard and written by Simon Barrett. The film stars Adria Arjona, Dan Stevens, Eric Wareheim, Reginald VelJohnson, Michael Biehn, Alex Pereira, Drew Starkey, and Rebecca Hall.

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.

As this is looking like a riff on Terminator it is great seeing Michael Biehn in the mix.

Onslaught is due out in the United States by A24 on 4th September 2026.
