The phrase "five across the eyes" is slang for "a slap in the face."
One night during filming, the production was stopped by the local police.
The film was shot in and around Morristown, TN. The same town that The Evil Dead (1981)was shot in 26 years earlier.
The teeth that Caroline spits out are real. Greg Swinson, the director's sister had two teeth pulled the day before filming began. So, his sister handed them over for the greater good of movie making.
The title "Five Across The Eyes" was inspired from the chorus of the song "Case Closed" by The Duskfall. During production, The Duskfall heard about the film and donated the song featuring the title phrase to the filmmakers.
