The license plate on the car Cal and Iris steal is from the vehicle 'John Cassavettes' drove in The Incubus (1981). The sheriff's name (Julian Karswell) seen on a reelection sign is the name of the antagonist in Curse of the Demon (1957) based on M.R. James' "Casting the Runes". This movie was filmed in less than a week during the beginning of March 2009.
