Creative geography, or artificial landscape, is a film editing technique invented by the early Russian filmmaker Lev Kuleshov sometime around the 1920s. It is a subset of montage, in which multiple segments shot at various locations and/or times are edited together such that they appear to all occur in a continuous place at a continuous time. Creative geography is used constantly in film and television, for instance when a character walks through the front door of a house shown from the outside, to emerge into a sound stage of the house's interior.
