Robert Redford and Sydney Pollack began a lifelong friendship and the beginning of an exceptional body if work together as actor and director both men having made their feature film acting debuts in War Hunt.
After making this film, Sydney Pollack devoted himself to his directorial career - he would make his feature debut in that capacity three years later with The Slender Thread. Pollack would not appear in a feature film again as an actor until an uncredited cameo in his own The Electric Horseman and then three years later in a very well received role in Tootsie that re-ignited his acting career.
Most of the film was shot at night to mask the budget limitations.
One of the truck drivers on the production was Francis Ford Coppola and one of the electricians was Noel Black.
Producer Terry Sanders sent the script to the Pentagon in the hope that they would provide some hardware assistance. The Army objected to many portions of the script including a private soldier being an independent professional killer with his commanding officer's approval, a captain calling a sergeant an idiot and several other scenes which the military felt were too gruesome to be in good taste.
Shot in only 15 days for a budget of $250,000.
