Trivia: Minor Spoilers for "Cult of Chucky." Series creator Don Mancini's original idea for "Child's Play 3" included multiple Chuckies. When Chucky's blood is accidentally mixed into the molten plastic, every single doll the assembly line produced was going to be possessed by Chucky's spirit. The idea was dropped for time and budgetary reasons, so only the first doll produced had his soul inside of it. Mancini always loved the idea, and was later able to implement a variation of it in the seventh film, "Cult of Chucky." (Although in that film, Chucky is able to possess multiple hosts at the same time thanks to a spell that more-or-less copy/pastes his spirit).

Question: At the beginning of the movie, the entire Good Guy factory is completely covered in dust and cobwebs because of not being used in eight years. What caused the factory to close for such a long time? Nobody believed Andy when he said that his Good Guy doll was possessed by Chucky. And even though Andy said Chucky was responsible for so many murders in his doll form, people most likely wrote it off as a child's overactive imagination and that wouldn't be enough to close down the factory.
