‘Onslaught’ Goes Full Retro With Killer New Character PostersThe marketing for Adam Wingard’s Onslaught continues to be a whole lot of fun, with A24 dropping a new batch of super retro character posters for the upcoming action-horror movie. And beyond looking like something pulled straight off the wall of an old-school video store, the posters give us some new character details and pairings. First up is the film’s “killer couple,” Dan Stevens as Dr. Kammler and Rebecca Hall as Frau Kammler. Adria Arjona leads the cast, with Stevens, Wareheim, VelJohnson, Biehn, Pereira, Drew Starkey, and Hall rounding out one hell of an ensemble. Onslaught unleashes hell in theaters September 4, 2026, from A24.
