In the scene when DJ buys drugs in Brian's apartment, the book that Brian is reading is "American Salvage" by Bonnie Jo Campbell. The book is a collection of short stories, most notably containing "The Solutions to Brian's Problem," which was adapted by director Bret Miller in 2011.
The script was originally written around 2000 as a short film. It was reworked into a feature around 2002, and was shelved until 2012. At that time, Director Bret Miller approached Writer Bill Vincent about producing the film.
In the opening scene, Mr. Walters (Dennis Kleinsmith) is appalled by the idea of his son getting a tattoo. Betty mentions how cool a long dragon tattoo would look on young Brian. In reality, it is Dennis Kleinsmith who has a large dragon tattoo on HIS arm. This was purely coincidental, as the tattoo gag was in the script long before Kleinsmith was cast.
