Trivia: Chucky almost always loses his right in the third act. In Child's Play, Andy's mom shoots it off. In Child's Play 2, Chucky tears it off to escape from a bar. In Child's Play 3, Andy cuts it off with a knife. In Seed of Chucky, his arms are cut off with an ax before he is beheaded. And in Cult of Chucky, one of the three Chucky's loses his right arm shortly before the climax. Of the seven films, five have Chucky losing either his right hand or entire right arm in the final thirty minutes.
Trivia: Minor Spoilers for "Cult of Chucky." Series creator Don Mancini's original idea for "Child's Play 3" included multiple Chuckies. When Chucky's blood is accidentally mixed into the molten plastic, every single doll the assembly line produced was going to be possessed by Chucky's spirit. The idea was dropped for time and budgetary reasons, so only the first doll produced had his soul inside of it. Mancini always loved the idea, and was later able to implement a variation of it in the seventh film, "Cult of Chucky." (Although in that film, Chucky is able to possess multiple hosts at the same time thanks to a spell that more-or-less copy/pastes his spirit).
Trivia: The film was announced, written, shot, edited and released less than nine months after the release of "Child's Play 2." The studio was worried about the series not lasting, and wanted to rush out a third movie as quick as possible to cash in on the success of the original. Series creator and lead writer Don Mancini (who wrote or co-wrote every single film and directed entries 5-7) has said "Child's Play 3" is his least favorite of the series, as he felt it pushed out too quickly and he didn't have the time to write a script he felt was satisfactory.
