This film that launched a decades-long franchise starts with 12-year-old Regan, the daughter a Hollywood starlet who gets her hands on a Ouija board and becomes a victim of demonic possession. While overtaken by the spirit, Regan swears, steals, and even pees on the floor. In her most iconic line, she tells an astronaut, "You're gonna die up there." And so, she undergoes a very trying exorcism.
