For Ran (1985), art director Yoshirō Muraki, constructing the "third castle" set under the director's supervision, created the "stones" of that castle by having photographs taken of actual stones from a celebrated castle, then painting Styrofoam blocks to exactly resemble those stones and gluing them to the castle "wall" through a process known as "rough-stone piling", which required months of work. Later, before shooting the famous scene in which the castle is attacked and set on fire, in order to prevent the Styrofoam "stones" from melting in the heat, the art department coated the surface with four layers of cement, then painted the colors of the ancient stones onto the cement.
