Vito Corleone
According to director Josh Cooley, Gabby was inspired by the Talky Tina doll from "The Twilight Zone" episode "Living Doll", who in turn was inspired by the Chatty Cathy line of talking dolls. Cooley also cites Vito Corleone from "The Godfather" film series as an influence for Gabby's control over the dummies who served as her enforcers.
