<P> The film was made in Beijing, with location shooting in the Anhui, Hebei, Jiangsu, and Xinjiang provinces of China . The first phase of shooting was in the Gobi Desert where it consistently rained . Director Ang Lee noted, "I didn't take one break in eight months, not even for half a day . I was miserable--I just didn't have the extra energy to be happy . Near the end, I could hardly breathe . I thought I was about to have a stroke ." The stunt work was mostly performed by the actors themselves and Ang Lee stated in an interview that computers were used "only to remove the safety wires that held the actors ." "Most of the time you can see their faces," he added, "That's really them in the trees ." </P> <P> Another compounding issue was the difference between accents of the four lead actors: Chow Yun - fat is from Hong Kong and speaks Cantonese natively, and Michelle Yeoh is from Malaysia and grew up speaking English and Malay; she learned the Mandarin lines phonetically . Only Zhang Ziyi spoke with a native Mandarin accent that Ang Lee wanted . Chow Yun Fat said, on "the first day (of shooting), I had to do 28 takes just because of the language . That's never happened before in my life ." </P> <P> Because the film specifically targeted Western audiences rather than the domestic audiences who were already used to Wuxia films, English subtitles were needed . Ang Lee, who was educated in the West, personally edited the subtitles to ensure they were satisfactory for Western audiences . </P> <P> The score was composed by Tan Dun, originally performed by Shanghai Symphony Orchestra, Shanghai National Orchestra, and Shanghai Percussion Ensemble . It also features many solo passages for cello played by Yo - Yo Ma . The "last track" ("A Love Before Time") features Coco Lee, who later performed it at the Academy Awards . The music for the entire film was produced in two weeks . </P>
