(at 1:13:27) Martin is on a bus looking at a newspaper. The main article about martial law declared in the U.S. features a photo that is actually from the G8 summit riots (July 20-22 2001 in Genova, Italy).
Actor Nick Damici carved the long bow used in the film from oak, on his kitchen.
Throughout filming, actor Nick Damici ("Mister") wore his mother's actual wedding ring on the pinkie of his right hand, as a way of acknowledging his character's back story.
At the beginning of the film, Martin puts on a Daniel Boone football helmet, which is a reference to directer Jim Mickle's high school.
This film was shot in two different portions with two months off in between both portions.
