All the soundtrack music in the film is stock music from the Hi-Q music library. Nicholas Coker learned that George Romero had scored Night of the Living Dead entirely with music from the library, so Coker set out to do the same with what he could find on the Internet Archive. All of the music used was written by William Loose and John Seely, and Coker even credited the duo as the film's composers, saying, "They deserved credit after all those thankless years."
In the original script, Sheldon enters the flower shop, only to be thrown out by the manager moments later. Despite having shot this version of the scene, Coker decided ultimately not to use it, as it would require working in a day-for-night effect (since they could only film during the day), and because the alternative scene where Sheldon slams against the door was simply funnier.
The main course of the dinner party is a bologna log sliced in half. Production designer Savannah Colbert found the recipe in a cookbook from the 1970's.
To raise money for the film, Nicholas Coker made a promotional video in the style of an episode of The Twilight Zone. The video opens with an animation resembling The Twilight Zone's intro and features Coker introducing the characters and scenario, channeling Rod Serling. Laura Stephens and Christian Bender appear in the video too, in the roles they would play in the film.
The Ford Thunderbird that appears in the film belonged to Nicholas Coker's neighbor. He saw the car in his apartment complex's parking lot and left a sticky note on it, asking if he could use it in the film. To his and the crew's delight, the owner was eager to participate.
