The production hired as many military and law enforcement veterans as possible. Both active and former Army, Navy, Airforce, Marines, DEA, FBI, CIA, CHP, Burbank PD personnel worked on the movie.
After watching the movie, Army Ranger Hall of Fame soldier Gary O'Neal said it was the most accurate depiction of what a veteran goes through when he comes home, that he had ever seen.
Before shooting, Marsden sent the script to various veterans for notes to make sure it was as authentic as possible.
This is the first movie in history to be shown at AAFES locations all over the world without a general theatrical release.
Matthew Marsden initially wanted someone else to direct the movie, but D. J. Caruso and Paul W. S. Anderson encouraged him to do it himself. They are both thanked in the credits.
