The town Sonny moves to is Stillwater, when she enters the town the sign states Stillwater's neighboring towns are Pertwilla and Poho. Both of those towns were places in Victor Salva's other movie Jeepers Creepers (2001).
Victor Salva wanted Gina Philips played Sonny Blake, even Salva adapted the character based on Philips' personality, but the role was ultimately awarded to Rose McGowan, due to Gina Philips being exclusively at her motherhood when production started.
The project was initially announced in 1999.
