Stanley Kubrick considered shooting the Dawn of man sequence on location in Southern Africa but was unable to due to the expense and also the likelihood of shooting being disrupted by adverse weather. Rear projection as well as colour separation overlay (blue-screen) were considered but not used because both methods would lack visual quality. Instead with assistance from MGM's special effects department the crew developed a new front projection system that used 8x10-inch slides taken on location in Africa. A high-intensity projector was aligned at a perfect angle from the camera and used to project the slide through a partially-transparent mirror that simulated placing the camera and projector in exactly the same place - thus the shadows cast by actors and set objects on the screen were invisible. However the screen material was only available in rolls of limited width and there were variations in reflectivity between rolls. Tearing the material up into small sections and "collaging" them together provided the best uniformity but with effort some variation can be seen in places.
