- Ishmael, like his sons, is named after a biblical figure. His name is a reference to the first son of Abraham in the Book of Genesis.
- The Polks seem to be based on the Peacock family from The X-Files episode, Home. Like the Peacocks, the Polks are murdering, deformed, inbred "hillbilly" characters dominated by a sexually abusive mother.
- Ishmael (To Audrey): "You killed Mama. She was the glue that held this family together. I'm gonna murder you real slow for what you done."
