Continuity mistake: When Carlos is killed by the three Chuckies with different weapons simultaneously, the editing gives away that three different prosthetic chest-pieces were used to accomplish the effect - one for each weapon. The blood and wounds on his chest and stomach are inconsistent from shot to shot as we see the different weapons slashing and stabbing him. His body also wriggles about a bit differently from shot to shot.

Trivia: During Nica's dream-sequence, at one point we see two brief glimpses of Chucky in extreme close-up screaming, with half of his face missing. This is actually cleverly-reused stock-footage from the end of "Child's Play 3" when Chucky is killed.
Question: At the end of Bride of Chucky, the Tiffany doll has a stitched scar on her forehead from being hit with an axe by Chucky. In the end of Cult of Chucky, the Tiffany doll is revealed and does not have the scar she had previously. What happened to it?
Answer: It's been years since the injury. Maybe she transferred her soul to another doll? Maybe she repaired her head? Maybe she copied her soul into another pristine doll as she can now inhabit multiple hosts at once? Take your pick, as it's a relatively insignificant matter.
