The movie contains no stock footage of any kind.
The crew used six different types of cameras to shoot the movie. These included the Red One, Red Scarlet, Red Epic, Canon 7D, Canon 60D, and the GoPro Hero.
Agent Nolan was originally set to be played by a different actor but when he suddenly quit the project after one day of shooting, Jacob Moore was bumped up from a supporting role to the main role.
Most of the costumes are simply Halloween costumes.
All the gunshots and muzzle flashes were created digitally, none of the weapons fired blanks. Blood splatters and bullet hits were also created digitally, without the use of squibs.
