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.
Trivia: The appearance of Charles Lee Ray on-screen during the flashback sequences marks the first time that Brad Dourif had appeared in human form in one of the "Chucky" films since the original. (Although photos of him from the original did subsequently appear in the other sequels, he had not shot any new live-action material in 25 years).
