Despite their long-running collaborative effort to bring Chucky to life, voice actor Brad Dourif and special effects wizard Kevin Yagher never met in person until they were both guests at a horror convention in May 2018.
The original working title for the film was "Batteries Not Included" before it became known Steven Spielberg was also making a film with the same title. It was then changed to "Blood Buddy" before settling on "Child's Play."
Catherine Hicks (Karen) and Kevin Yagher (Chucky's creator) met on set and were married a year later.
Originally the studio billed Chris Sarandon as the top star over Catherine Hicks, but Sarandon requested that Hicks be top billed, since he felt she carried the picture.
During the initial release, a crowd of protesters formed around the entrance to MGM, calling for a ban on the film. They claimed it would incite violence in children. Local news reporters were broadcasting live from the scene, and the producer David Kirschner was watching, disturbed by what he saw. Jeffrey Hilton, who worked with Kirschner at MGM, said he could defuse the situation in ten minutes. Hilton went down and spoke to the ringleader and then the group disbanded, to the chagrin of the newscasters. Hilton never specified whether it was threats or diplomacy that saved the day.
