In The Exorcist, Regan (Linda Blair) is a young girl possessed by the demon Pazuzu and requires an exorcism to free her. Although you may be able to recreate Regan’s demonic look, it isn’t quite the same without the head spinning and projectile vomiting.
In The Shining, Jack Torrance is looking forward to a quiet winter as the off-season caretaker of the Overlook Hotel, allowing him to focus on his writing and to spend some quality time with his family. That is until he becomes influenced by supernatural powers. Heeeeere’s Johnny!
