Ultraman: The Ultimate Hero

The series' staff actually planned on using refrigerator boxes with simple square "windows" cut out, to create cheap-looking cardboard buildings (to play up a "campy" effect, and reflect the preconceived American notion that the buildings in Japanese monster movies were made of cheap cardboard boxes, which is not true; buildings destroyed were usually made from a combination of thinly cut plaster and wood), but Tsuburaya, shocked from hearing this, quickly sent a crew over to the US to create actual detailed miniature buildings for the production.
