‘Child’s Play 2’ (1990)

"Child’s Play 2" was, arguably, equal parts creepy and funny, and this careless mistake definitely adds to the campy fun. When Grace (Grace Zabriskie) grabs Chucky in her office during a human-on-possessed-doll struggle, Chucky ultimately wins and stabs her twice, after which, Grace stumbles backwards. It’s then that the top of a crew member’s head finds its way into the shot. Someone’s hair must’ve wanted its 15 minutes of fame.
