There are two references to The Changeling (1980). The first is when a little girl is playing with a red and white rubber ball (it looks very similar to the one in the former film). The second and most prominent reference is when a mental patient is being dragged away, kicking and screaming while a guard taunts him with the following line, "Time for your bath, Carmichael!" The actor playing the patient is none other than Voldi Way, who played Joseph Carmichael in The Changeling when he was a kid.
