Belgian Surrealist painter RENE MAGRITTE provoked creative tension by combining familiar things in unfamiliar combinations.
In a series of paintings called "The Empire of Light / L'Empire des Lumières" (1950-'54), the jarring tension comes from a daylight sky resting over a night street scene.
Director William Friedkin saw this image in a book shared by actor Ellen Burstyn while filming "THE EXORCIST" (1973).
It inspired this iconic poster; a subtly transgressive image of the forces of light (a shadowed priest, below) confronting the forces of darkness (a lit window, above).*
That poster clearly haunts this poster for "THE POSSESSION" (2012).
* The Magritte painting also inspired the cover for the Jackson Browne album, "Late For the Sky" (1974).
