More mistakes in Child's Play 3
Chucky: Don't fuck with the Chuck.
Trivia: Chucky almost always loses his right hand/arm 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.
Question: Why didn't Alex Vincent reprise his role as Andy?
Answer: To add to the other answer, the writers and producers felt that after two movies they had gone as far with child Andy as they possibly could have. They felt it would be too redundant to have a third film with Andy as a kid being pursued by Chucky. So they set this film years later when Andy was a teenager.
Answer: The film makers wanted to make Andy older in the film so he could have a love interest and be in military school. At the time Alex was only 9, but they wanted Andy to be 16. So they recast the part.
