Plot hole: When Chucky is decapitated, no blood comes out. He still has the scars from Bride/Seed of Chucky so that means he's still in the same doll's body. The longer he remains inside the doll the more human he becomes, so he should definitely bleed by this point in time.
Curse of Chucky (2013)
1 plot hole
Directed by: Don Mancini
Starring: Brad Dourif, Alex Vincent, A Martinez, Danielle Bisutti
Continuity mistake: Barb's eyes are green throughout the movie, but when Chucky stabs her in the eye, the eyeball that rolls down the steps is blue.
Trivia: Had the longest timegap between sequels, coming out nine years after the previous film, "Seed of Chucky." The long wait was in part because a few years after "Seed" was released, several attempts were made to remake/reboot the series, given the rising popularity of 80's slasher-film reboots. Despite several false starts, the reboot never happened. Eventually, series creator Don Mancini opted to instead perform a "tonal reboot" of the series with this film - by setting it in the same "universe" as the other movies, but shifting the focus back to classic horror and delivering a film more tonally similar to the original 1988 film. Mancini wanted to please fans, who expressed interest in seeing another "scary" Chucky movie after the previous two films had become increasingly comedic in tone.
Question: When Chucky killed Barb onwards, where was Alice? Was she in the house, or did she runaway to her gran's at the end?
Answer: It is revealed when Ian checks the webcam that Chucky hid Alice in the closet. She was most likely there the whole third act.
Answer: When Ian is checking the nanny cam, it is reveals that Alice is playing Hide-And-Seek with Chucky, instead of sleep. Chucky hid Alice in a closet, to keep her is not on his way while he is murdering the family.
Suggested correction: There's no telling exactly how his Voodoo works.
The writer/director even admitted this scene was a mistake. Prior films showed that once Chucky inhabited the doll for long enough, blood and organs would appear. The director simply chose to ignore this for this one scene, and has admitted it's a mistake.
