Continuity mistake: Early in the film when the Chucky doll is being rebuilt, he is put together limb by limb and has a hard plastic body. When the doll is complete and seen in later scenes throughout the movie he has floppy arms and legs which would indicate a stuffed soft body doll. The good guy doll was shown as a soft body doll several times in the first film, like when Maggie picks him up from from in front of the TV by his arm. (00:03:10 - 00:15:30)

Continuity mistake: Chucky's eyes are made so that they blink and move. However, in the scene where the business man is stuffing Chucky into the trunk of his car, Chucky's face is different because his eyes are drawn onto his face. The same thing happens with his mouth throughout the movie. (00:14:35)
