 Iguazu Falls was a natural location depicted in the film, although as stated by "Q" in the film, the falls were intended to be located somewhere in the upper basin of the Amazon River rather than where the falls are actually located in the south of Brazil. The second unit had originally planned on sending an actual boat over the falls. However, on attempting to release it, the boat became firmly embedded on rocks near the edge. Despite a dangerous attempt by helicopter and rope ladder to retrieve it, the plan had to be abandoned, forcing the second unit to use a miniature at Pinewood instead. The exterior of Drax's pyramid headquarters in the Amazon rain forest near the falls was actually filmed at the Tikal Mayan ruins in Guatemala. The interior of the pyramid, however, was designed by Ken Adam at a French studio, in which he purposefully used a shiny coating to make the walls look plastic and false. All of the space centre scenes were shot at the Vehicle Assembly Building of the Kennedy Space Center, Florida, although some of the earlier scenes of the Moonraker assembly plant had been filmed on location at the Rockwell International manufacturing plant in Palmdale, California.
