The city shots of Metropolis were a combination of both two and three dimensional elements, consisting of matte drawings and paintings, flat wooden relief models, and three dimensional models scaled to 1/16th of the simulated heights. All matte drawings of the cityscape were scaled to a height of 1/100. The man responsible for most of the film’s models was Walter Schuzle-Mittendorf. The set designers- Otto Hunte, Erich Kettelhut and Karl Vollbrecht- first created a number of concept drawings for the imagined city of Metropolis, following Lang’s plan for the city to be divided into several sections. The emphasis was on the verticality of the structures, intersected by roadway systems and aircraft. The dominating architectural feature is the so-called New Tower of Babel, the largest building located centrally in the city. The building, like most of the buildings in the film, is a model.
