Visible crew/equipment: When Chucky has the voodoo doll of John, he walks along, then says "And you have a date with death!" After saying that, he turns, prior to stabbing the voodoo doll. After he says it, and turns, you can see the large, bald, shiny head of a puppeteer, crouched behind him!!
Visible crew/equipment: At the end of the film, the burnt head and body of Chucky are thrown across Karens bedroom, below the window. The body twitches, then suddenly jumps up. The body's (one) leg actually doesn't touch the ground! The body rises with no real support, so if you look under the body, you can see a black rod/sheet (coming from through the carpet), pushing the burnt body up.
