Movies and ghosts go together like popcorn and butter. First appearing on film in the late 1800s (yes, you read that right), ghosts are now employed as the mysterious, terrorizing force in many blockbuster hits and indie art films alike. Malevolent, grief-stricken, mischievous, and bestowed with oodles of unfinished business, cinematic ghosts torment home-owners, stalk trespassers, haunt memories, and come when summoned — perhaps never to leave again. Once you see dead people, only one question remains: Do you try to help them, or do you try to make them go away? This video takes a compassionate look at an oft-misunderstood onscreen monster that truly crosses the threshold of this mortal coil.
