Linda Blair (born January 22, 1959) is an American actress famous for her role as the possessed child in The Exorcist. and its first sequel, Exorcist II: The Heretic.

She did not receive the Academy Award for the role and it is thought that this was due in part to the fact that the demon voice was dubbed (Mercedes McCambridge) and a double (Eileen Dietz) was used in many scenes. Linda Blair began her career as a young child modelling and then moved into commercials. Blair had originally planned to be a doctor but was offered The Exorcist role.
