Trivia: The decision to turn the Child's Play/Chucky franchise from a slasher-horror to a dark comedy series was inspired by several factors. In addition to 1996's meta horror-satire "Scream" making self-aware horror-comedies popular, series creator Don Mancini also felt that by the time "Child's Play 3" had come out, Chucky had become such a pop culture icon, he might never be properly "scary" ever again, since people were too familiar with him. And thus, in order to keep the series fresh, he and producer David Kirshner decided to make the fourth film more comedic and self-aware in tone.
Trivia: The "Voodoo for Dummies" book Tiff reads was a prop made for the movie. The apparent author is Don Mancini, the script writer. There is however a "Complete Idiot's Guide to Voodoo".
Trivia: The opening scene at the evidence depository that shows things like Michael Myers' mask and Freddy Krueger's glove was originally written for "Child's Play 2," which was meant to open with a courtroom scene. The scene would have shown Chucky's remains being collected and taken to court. However, the scene was cut. Series creator and writer Don Mancini really loved the idea of an evidence locker full of references to other horror movies, so he reused it as the opening scene for this film.
