Chill Factor is a 1999 American buddy action comedy thriller film directed by cinematographer Hugh Johnson (in his only directorial effort) and starring Cuba Gooding Jr. and Skeet Ulrich.

Ten years after one of Dr. Richard Long's military experiments went wrong and killed eighteen US servicemen and a medical assistant, he has become a recluse in the small town of Jerome, Montana.

The two don't get along with each other—Arlo only agrees to transport the substance in his ice cream truck because Mason held a gun on him—but they find a common bond in trying to avoid Brynner and his team.

With the help of Colonel Leo Vitelli, Arlo and Mason try to survive Brynner's attacks, avoid the local deputy, Pappas, and keep "Elvis" below fifty degrees.

Arlo and Mason finally reach the base, but get ambushed by Brynner and his team who plan on detonating the device in an abandoned weapons test facility.

Colonel Vitelli arrives and congratulates them on a job well done, but Arlo and Mason threaten to expose the U.S. government for using unstable nuclear weapons for the past decade.
