The monster, whose design is inspired by three species of endangered monkeys, can transform its size, growing to giant proportions.
When shooting the sequences featuring the monster in its normal size, Koo says he actually performed with a martial arts choreographer who wore blue suit, specifically designed to be replaced by the digitally-made creature during postproduction.
The film also stars Chen Xuedong, Bea Hayden, Bao Bei'er, Wang Taili and Zhou Dongyu.
