Onslaught (2026)

The Onslaught teaser trailer is for the A24 action horror film directed by Adam Wingard and written by Simon Barrett, the team behind You're Next and The Guest. Set in the same world as The Guest, it follows an army sniper, played by Adria Arjona, who has to protect her young daughter when a group of genetically engineered super soldiers escapes from a secret military facility and goes on a rampage. Dan Stevens, the star of The Guest, is back, alongside Rebecca Hall, Eric Wareheim, Drew Starkey, UFC champion Alex Pereira, Michael Biehn and Die Hard's Reginald VelJohnson. It is a fast, violent, 93-minute ride with a retro 1980s action feel. A24 released it in theaters on September 4, 2026, and it is now available on digital.
