Tony Leung Chiu Wai in the film THE SILENT WAR (TING FUNG JEH) played a blind piano tuner with exceptional hearing; by chance he runs into the Zhou Xun played 701 Operation Office member who leads him to become an important member. Wai Jai in the film has to give up his pair of mesmerizing eyes, which are covered up with sunglasses and bandages.
He said, "Without exchanging looks, this character is very hard to play; with the depiction of my insight about my surrounding environment with exceptional hearing, early in the shoot I need some time to grasp the character."
THE SILENT WAR is the second collaboration between Wai Jai and Zhou Xun. Zhou Xun said that this time they could not act with their eyes, which was somewhat difficult; yet they had more lighter and more humorous spots and she and Wai Jai got along very well.
The film shot on location in Shanghai. Wai Jai at first had to acclimatize and was often nauseous on the set. He did not want to affect the shoot and worked while he was ailing. Directors Alan Mak Siu Fai and Felix Chong Man Keung praised his professionalism and Zhou Xun for her much improved acting.
