The knife Charles Lee Ray uses during the flashback is the same knife he uses throughout the first Child's Play film.
Fiona Dourif, who plays Nica, is the daughter of Brad Dourif who voices Chucky.
Brad Dourif recorded all of his lines in less then a day.
This film was shot in 30 days.
The longest time in the series before Chucky speaks his first lines.
The makers had a practical joke at a bus stop to promote the film. A billboard of the movie's poster would light up and an actor dressed as Chucky would suddenly bust through the billboard and scare whoever was nearby.
With a runtime of 97 minutes, it's the longest film in the series.
Only four of the eight of Chucky's staple scars are unearthed in the attic scene that existed from Bride of Chucky. There are three more on his head and one on his right hand.
At points during filming, Chucky's face had to be covered with tape because it legitimately scared the actress playing Alice.
Nica's father's death is only shown in a deleted scene.
The first time Chucky tries to possess a female.
Amelia Jackson-Gray and Jacinta Yelland auditioned for the role of Nica.
The elevator in the house is similar to the one in the apartment complex in the original Child's Play.
This marks the first time a child doesn't realize that Chucky is evil.
When production was first announced, Scott Patterson was strongly rumored to have a role in this film, but nothing ever surfaced.
Even though she plays Nica's mother, Chantel Qusiniel is only 10 years older then Fiona.
Nica is the first main character to be in a wheelchair.
When Chucky electrocutes Jill to death, a huge burn appears on her right eye that's very similar to the mark on Chucky's scarred face, which the audience doesn't see until later on in the film.
After Tiffany kills Officer Stanton she says "they never learn" this is a reference to her previous killing in Bride of Chucky (1998) when Officer Bailey attempted to take a peek at Chucky's remains until Tiffany slashed his throat with her nail file.
