Theater mistake

This film caused some problems when it was accidentally shown in place of the children's film The Last Mimzy at a Holtsville Long Island cineplex in April 2007.[3] Since the first scene happens before the credits, there was no warning for what was about to be shown, which was a graphic birth scene, after which the mother is clubbed to death by a mutant.
