Attack of the Unknown

Attack of the Unknown (2020) is an American sci-fi action-horror you can watch online on iFILM. A SWAT team is moving a vicious crime syndicate boss when an alien invasion rips open the sky above them.

The unit gets pinned down inside a county detention center as the city falls apart outside. Comms drop, the exits seal, and the cops are suddenly caught between two threats — a dangerous prisoner they can't afford to lose, and something far worse closing in from the dark. As the tagline puts it, the visitors are here for blood. The only way out runs through both.

Director Brandon Slagle leans into lean B-movie territory: tight corridors, gunfire and a creature threat standing in for a big budget. It's aimed at fans of pulpy invasion flicks who want momentum over realism. Tara Reid, Robert LaSardo and Richard Grieco head the cast. Stream Attack of the Unknown (2020) online on iFILM.
