Long before the days of CGI, the team responsible for bringing Chucky to life in the original Child’s Play had to get incredibly creative, utilizing various techniques to make it appear as if the killer doll was actually walking, talking and slashing. It’s quite a remarkable film in the effects department, that’s for damn sure, and it all still holds up well to this day.

Not only were animatronics effects used to animate the Chucky doll, but a couple of different performers actually played the pint-sized killer doll for a handful of moments that required more advanced movements than even effects wizardry could provide. Notably, Ed Gale is credited for playing Chucky in the original, but a 2-year-old kid also helped out!

Detailed in a recent piece on THR, “Humans in costume also filled out the doll’s range of movement abilities, a simple yet effective ploy that tricks the audience just as they think they have a bead on the doll’s range of movement capabilities. One brief moment in which Chucky runs behind the furniture actually featured one of Kirschner’s close neighbors; two-year-old Hunter Marks was dressed in a wig and overalls, running to the arms of his mother.”

“I think it’s one of the great creepy shots of all time,” director Tom Holland told the site.

Within the piece, THR include a photo of Hunter Marks on set in the full Chucky costume, which I personally had never seen before. It’s pretty wild, and you can check that out below!
