There is an after-credits sequence at around 1:29:30.

The writers intended the movie to be a Saw (2004) prequel, but the idea was declined.

Originally set-up and financed by Dimension Films, "The Collector" was dropped by the cash-strapped studio after they didn't have the funds to release the film. Lidell Entertainment snatched up the rights from Dimension and gave the film a brief, but successful, theatrical run in 2009.

Like "Saw" (2004), this film is also inspired by "Se7en" (1995).

The Collector urban legend is really a catch-all legend for creepy hermetic neighbors that may be doing something horrifying inside their dungeon-like basements. The most common "Collector" legend is the neighbor who collects human body parts and proudly displays them in mason jars. In Russia, the Collector urban legend has a bright future because it played out in real life. Its new mascot is local Russian historian Anatoly Moskvin, who stole corpses from cemeteries in dozens of towns east of Moscow. According to police, he dug up at least 29 corpses and made dolls out of them-life-sized faceless female dolls with platinum blond wigs.
