Practical and old school special FX are becoming a lost art, but the makers of the Child's Play reboot have revealed the movie will embrace animatronic effects for its main character, the murderous doll Chucky.

In the latest trailer for Child's Play, which was released by Rotten Tomatoes, the movie's director Lars Klevberg provided pop-up production notes that go into the film's techniques and inspirations. "I will say almost 80 percent of Chucky in this movie is done with animatronics," Klevberg says in the video.

Though voiced ultimately by Mark Hamill, during filming Chucky was voiced by his puppeteer to help star Gabriel Bateman's performance. According to Klevberg, "On set Chucky was controlled and voiced by the lead puppeteer so Gabriel who plays Andy could interact with the doll and also improvise during takes."

Klevberg also explained this reboot is inspired by 80s classics such as E.T. and Gremlins, as well as international cult classics Attack the Block and Let the Right One In. Klevberg referred to his film as "E.T. on acid," and references to Spielberg's beloved classic are sprinkled throughout, one being Andy's red hoodie.

Directed by Lars Klevberg from a script by Tyler Burton Smith, Child's Play stars Aubrey Plaza, Brian Tyree Henry, Gabriel Bateman, Tim Matheson and Mark Hamill. The film opens on June 21.
