 Designing continued throughout production, such as Gollum's redesign in May 2001 and the Great Beasts in early 2003.The backstories of several of the cultures depicted in the films had to be shown through only subliminal glimpses on screen, as are the miniatures, and for the Elves and Gondorians, fictional histories had to be presented within the changes of armour.The Elves have an Art Nouveau influence that involves leaves and flowers, while the Dwarves have a preoccupation with geometry that was intended to remind the audience of their digging nature.
