Project Viper is a 2002 movie starring Patrick Muldoon, Theresa Russell, Curtis Armstrong, Tamara Davies. The movie was directed by Jim Wynorski under the pseudonym "Jay Andrews."
When a terrifying, bioengineered lifeform is stolen from its creator, the military calls on a covert troubleshooter to destroy it before it decimates a small town in its path, and then the rest of the world.
The space shuttle Olympus is on a routine mission, but with a far-from-routine payload: "Project Viper," an experimental hybrid of human genes and computer chips, designed to adapt to any environment, particularly that of Mars. But as the shuttle crew prepares to launch the prototype into space, something unexpected occurs. Soon the astronauts are dead, and the Secretary of Defense orders the remaining prototype destroyed. To do the job, he calls on devil-may-care special agent Mike Connors (Patrick Muldoon).
Unaware of these proceedings, Project Viper head Nancy Burnham (Theresa Russell) and her team at NovaGen — Steve Elkins (Billy Keane), Sid Bream (Tamara Davies) and Alan Stanton (Daniel Quinn) — are celebrating the fruition of their scientific dream. One more member, Cafferty (Lydie Denier), is on her way — but never makes it. Soon the second prototype is stolen from the high-security NovaGen lab by those who waylaid her — and whatever killed the astronauts is on its way aboard a stolen plane toward.
Wherever it was headed, it did not arrive. The deadly, highly adaptable prototype, having escaped into a lake near the town of Lago Nogales, begins feeding on the unwary populace (including Playboy model and pin-up girl Lorissa McComas, playing a young lover in a pickup truck). Connors, Burnham and crew arrive to find a suspicious sheriff (Tim Thomerson), mysterious disappearances, gooey remains, unpredictable genetic side-effects, treason and murder — while the clock ticks down as the military prepares a nuclear strike to keep the ever-growing Viper from wiping out life on Earth.
The monster is a large pile of gray goo (a reference to the gray goo theory) that can move around and create different forms of itself. It is controlled by a computer chip that can be turned off by a remote control, rendering the creature harmless. It kills and eats by getting into people's bodies and eating them from the inside out.
