The Exorcist (1973)

The Exorcist (1973), directed by William Friedkin, remains the gold standard of horror cinema. Based on William Peter Blatty's novel, this chilling masterpiece follows a 12-year-old girl's demonic possession and the desperate exorcism performed by two priests. Its groundbreaking practical effects, disturbing imagery (including the iconic 360-degree head turn), and psychological terror caused fainting spells and heart attacks during its original release. Nominated for 10 Oscars and winning 2, it was the first horror film nominated for Best Picture. The Exorcist's profound exploration of faith versus evil, coupled with Linda Blair's unforgettable performance, continues to haunt audiences five decades later, maintaining its status as cinema's most terrifying experience.
