Poltergeist (1982)

Strange and creepy happenings beset an average California family, the Freelings -- Steve (Craig T. Nelson), Diane (JoBeth Williams), teenaged Dana (Dominique Dunne), eight-year-old Robbie (Oliver Robins), and five-year-old Carol Ann (Heather O'Rourke) -- when ghosts commune with them through the television set. Initially friendly and playful, the spirits turn unexpectedly menacing, and, when Carol Ann goes missing, Steve and Diane turn to a parapsychologist and eventually an exorcist for help.
