The Exorcist
In the heart-stopping horror classic The Exorcist, Regan MacNeil (Linda Blair), a young girl, becomes inexplicably ill. After all medical explanations are exhausted, her mother Chris (Ellen Burstyn) seeks help from two priests. Father Karras (Jason Miller), a troubled cleric wrestling with his faith, and veteran exorcist Father Merrin (Max von Sydow) step in to confront an evil beyond their understanding. The film, directed by William Friedkin, is recognized for its chilling portrayal of possession and exorcism. It won two Academy Awards and remains one of the most influential horror films to this day.
