The Terror Within is a 1989 American science fiction horror film directed by Thierry Notz and starring George Kennedy, Andrew Stevens, Starr Andreeff and Terri Treas.

It was followed by a sequel in 1991, The Terror Within II, with Stevens reprising his starring role while also handling the film's writing and directing duties.

Two of these survivors Michael and John are out surveying the world after a chemical or biological attack which left a large portion of the population mutated or dead.

Over the radio, their colleagues, Hal, Andre, Neil, Sue, Linda and David hear John and Michael fall under attack from the gargoyles while investigating a large group of buzzards.

David and Sue learn that Karen is the last remaining member of a group of survivors who were attempting to seek asylum at the Rocky Mountain Lab.

The two surviving humans are able to lure the gargoyle into the ventilation system where he becomes trapped and falls into a running exhaust fan dismembering him.

David and Linda re-establishes radio contact with the Rocky Mountain Lab and along with a healed Butch leave the bunker with a high frequency megaphone to brave the outside world.

Before leaving, they lie in wait for a number of gargoyles to enter the open bunker and implode it with remote controlled explosives.

Factory released the film on DVD, packaged as a double feature with Dead Space, as part of the Roger Corman's Cult Classics collection.
