Seed of Chucky is a 2004 American black comedy slasher film, the fifth installment of the Child's Play series, and sequel to 1998's Bride of Chucky as well as the first film to be distributed by another company since Child's Play. The film was written and directed by Don Mancini, who created the series and has written all of the films (except the 2019 remake). With this entry, Mancini made his directorial debut. The film is set six years after Child's Play 3 and Bride of Chucky and follows a young doll named Glen, the son of Chucky and Tiffany, resurrecting his parents, causing chaos.
The film, shot in Romania, continues the series' evolution from the pure horror genre of the first three films to a hybrid horror-comedy. It was the last Child's Play film from the original continuity to be released in theaters, with all future installments to be released direct-to-video until the 2019 remake, fifteen years later. The film was followed by another sequel, Curse of Chucky, released on home video and Netflix in 2013.
Seed of Chucky was a commercial failure, grossing $24 million against a $12 million budget. It received generally negative reviews, with chief criticisms being directed towards its plot and humor.
Six years after the previous film, Glen, the benevolent son of Chucky and Tiffany, has a nightmare in which he murders a little girl's parents. In reality, he is living a life of embarrassment and abuse as a ventriloquist's dummy in England. After being forced to perform at the International Ventriloquists' Competition in Glastonbury, and then locked inside a cage, Glen sees a preview of Jennifer Tilly's new horror film Chucky Goes Psycho, based on the Kincaids' encounter with Chucky and Tiffany on television, including Chucky and Tiffany dolls rebuilt from their original remains, and realizes that he is their son.
Desperate to know his parents, Glen manages to escape his abusive owner and tracks the Chucky and Tiffany dolls to Hollywood. He finds himself in the prop room of Chucky Goes Psycho, which contains the Chucky and Tiffany dolls. Glen uses the Heart of Damballa, a voodoo amulet to bring them back to life. Chucky faints, but Tiffany is overjoyed and hugs her child. When a puppeteer starts taking Tiffany apart, she and Chucky decapitate him with a piano wire. Jennifer finds the beheaded body and calls the police. Chucky, Tiffany, and Glen ride home with her in a limousine.
Having witnessed his parents kill the puppeteer, Glen asks them why they murder others, as he feels violence is bad. Chucky replies that it helps them to relax. On the other hand, Tiffany, feeling parental responsibility, agrees with Glen and forces Chucky to agree to stop killing people for the sake of their son. Chucky promises to do so, but crosses his fingers behind his back in hopes of getting Tiffany to shut up. Jennifer tries to get a role as the Virgin Mary in Redman's directorial debut, and after he tells her she is not right for the part and picks Julia Roberts instead, she invites him to her house.
Chucky and Tiffany make plans to transfer their souls into Redman and Jennifer. As Jennifer and Redman start to make love, Tiffany knocks them out and uses a turkey baster to inseminate Jennifer with Chucky's semen. Chucky takes Glen on a car ride. After driving Britney Spears' car off the road, killing her, they proceed to photographer Pete Peters' darkroom. Peters had taken pictures of Tilly kissing Redman and of Chucky masturbating. When Glen tries to warn Peters that Chucky is about to attack, Peters bumps into a shelf, causing a jar of sulphuric acid to fall into his head, accidentally killing him. Chucky, overjoyed with pride, believes Glen did this on purpose and takes a picture to celebrate, much to the dismay of both Glen and Tiffany. Jennifer awakens the following morning, realizes that she is pregnant, and claims Redman is responsible. Redman denies this, as he reveals that he had a vasectomy prior so he can't possibly be the father, leaving Jennifer horribly confused. Tiffany eviscerates him in anger. The next day, Jennifer wakes up only to find herself with a full pregnant belly, a consequence of the voodoo magic. Chucky attacks and captures Jennifer during a phone call. Her chauffeur, Stan, serving as Chucky's replacement body due to Redman's death, is also captured. Jennifer's assistant Joan tries to help her, but she is killed by Glen's murderous twin sister, Glenda, whose soul shares Glen's body. Tiffany discovers this and smacks Glenda to bring back Glen, who is horrified at what has happened.
After Jennifer gives birth to twins, a boy and a girl, Chucky has an epiphany: after years as an infamous killer doll, he finally accepts his circumstances. Disgusted, Tiffany rejects Chucky and decides to take Glen with her. Enraged, Chucky throws a knife at Jennifer to stop Tiffany transferring her soul into her body and leaving him, but Stan jumps in the way to save her and tells Jennifer he loves her before dying. The police arrive, forcing the dolls to flee. Jennifer is rushed to the hospital, but claims she wants to see her babies. Tiffany drugs Jennifer and begins to possess her, but Chucky breaks in and kills Tiffany with an axe. Before Tiffany dies, she tells Glen not to make the same mistakes she and Chucky have. Devastated, Glen snaps and challenges Chucky to a fight. Jennifer passes Chucky's axe to Glen, and Glen impales Chucky. Chucky assumes it's Glenda again, but Glen reveals it is actually him, finally able to kill in revenge for his mother's death. Chucky soon congratulates Glen, but he chops off his head. Realizing what he had done, Glen suffers an emotional breakdown as Jennifer comforts him. Five years later, at a birthday party for Jennifer's children, a nanny quits her job because Jennifer's daughter Glenda scares her. Jennifer lets the nanny quit, only to beat her to death with the Tiffany doll. Jennifer's eyes glow green, revealing that Tiffany was successful in transferring her soul into Jennifer's body. Glen has one more birthday present to open, from an anonymous source. When he does so, Chucky's severed arm is revealed to be inside, which springs up to grab him as Chucky’s infamous laugh is heard as the screen fades to black. Following this is a closing montage featuring clips of the characters, accompanied by a cover of the song One Way or Another.
