Scale models of structures were constructed by Emilio Ruiz and positioned in front of the cameras so that they appeared as full-sized structures on film; using this technique, the Shadizar set was extended to appear more than double its size.
Os modelos e estruturas a escala foron construídos por Emilio Ruiz e situáronse diante das cámaras para que semellaran estruturas de tamaño completo; usando esta técnica, o escenario de Shadizar puido aparentar máis do dobre do seu tamaño real.
