Trivia

The website used by the killer (www.killwithme.com) actually existed. It was owned by the movie studio and it was used to promote the film. In it, users were taken to a replica of the FBI computer used by the character Jennifer Marsh. Her desktop gets hacked by the killer who provides the visitor with four tests he/she must complete to deactivate his website. The content has now been removed, and the domain name is available for sale or lease. See more
