Jared Kovacs and Mills were inspired to shoot in 4:3 after watching VHS movies on an old TV, including The Hitcher which also inspired the final shot of the film.
The original script featured Mr. Patch as the one who tortures the deadbeats to death. In a rewrite Mills worked on with writer Chris Ruffin, the drug dealer character was added to the narrative.
Mills was actually tazed during takes in the gun shop scene.
