this was one of my favorite horror movies in the 80s directed by Wes Craven it was about a new kid in the neighborhood who was a genius, built a robot but the robot was destroyed by a mean old lady across the street with a shotgun. and later in the movie the girl next door is accidently by her father pushed down the stairs and is pronounced Brain dead by the doctors so the smart kid sneaks in before they pull the plug and plans on putting the brain of the robot in the girls head but hes to late still does the job but she becomes zombie like and kills the people that did the robot and the girl harm. it had a young (16 maybe) Kristy Swanson
in it and the robot, BeBe was cool as hell and voiced by Charles Fleischer (roger rabbit) if there is any news of the underated film on DVD id love to replace my aging taped of of HBO copy:p
