- Actor Allusion:
- Fan Nickname: Chucky: Chuckynort, for reasons that are spoilers to both Cult of Chucky and Kingdom Hearts 3D: Dream Drop Distance.
- The Other Darrin:
- In the Japanese dub, Bin Shimada replaces Rokuro Naya as Chucky, as the latter passed away between the dubs of the last film and this one. Keep in mind Naya has voiced him since the second film onwards. Andy is voiced by Mitsuru Fujiwara, replacing Yuuichi Karamaru from the previous film. Oddly enough, Mika Doi reprises her role as Tiffany from Bride of Chucky, since in the last film she appeared, she was voiced by Shinobu Adachi instead. The only character from the previous film whose VA reprise his or her role is Chie Nakamura as Nica.
- In the Brazillian dub, Guilherme Briggs voices Chucky, replacing Nelson Machado, who's been voicing Chucky since Bride.
- Technology Marches On: Chucky used to get his voodoo spells from instruction manuals in the older movies. Now he learns new spells on the Internet on VoodooforDummies.com.
- Write Who You Know: The character Carlos is based on a friend of writer and director Don Mancini's, who is also a gay Latino nurse.
