According to writer John C. Kruize, the original story (while under the title "The Pestilence") "concerned secretive and illegal germ warfare research being conducted by the U.S. military in a remote area of the Rocky Mountains. A lab worker is infected by some type of mutant flu virus and carries the contagion to an isolated town." He admits Stephen King's novel "The Stand" was an influence. See more »

A Very scary classic. Underatted. But a small-Fraud.
12 August 2000 | by (Lake Isabella, CA) – See all my reviews

NIGHT SHADOWS was infact a creepy little film it was kind of like that other film THE DARK. NIGHT SHADOWS (MUTANT) could be a long-awaited sequel to that film. Well unfornatly this is an Edward L. Montoro production in this case I had a feeling it was going to be a fraud he dose this with every film he makes and gets a law-suit filed againist him inculding GREAT WHITE (1980) BEYOND THE DOOR (1974) and THE DARK which was not pulled like his other movies. He also had a suit with William Girdler over DAY OF THE ANIMALS and GRIZZLY for profits. Well even though this movie was a Montoro production I still enjoyed it. It was okay. Especailly the mutants taking over the people of a small town and John Cardlos direction.

Montoro later in 1985 went to produce GRIZZLY II THE PREDATOR and released in 1986. His law-suits over the years was still effective aganist him he left the country in 1987 and was never seen again.
