The Exorcist (The Exorcist Extended Director's Cut and Original Theatrical Version) (Blu-ray)

When young Regan (Linda Blair) starts acting odd--levitating, speaking in tongues--her worried mother (Ellen Burstyn) seeks medical help, only to hit a dead end. A local priest (Jason Miller), however, thinks the girl may be seized by the devil. The priest makes a request to perform an exorcism, and the church sends in an expert (Max von Sydow) to help with the difficult job.
