Hero

The "red fight" between Moon and Flying-Snow was filmed in a forest in Mongolia. Director Yimou Zhang had to wait until the leaves turn yellow, and hired local nomads to gather even more yellow leaves in order to cover the ground completely. In fact, he was so fanatic about the leaves, that he had his crew separate the leaves into four different "classes" which were each put at increasingly farther lengths from the camera.

At the beginning of the movie, subtitles state that China was divided into seven warring states. At the end, the subtitles then state that "the King of Qin" unified China, without specifying which one. Historically, the king that was the one to unite all of the Chinese states was Ying Zheng (later changed name to Shi Huang Di) who inherited the throne from his deceased father at age 13 (as opposed to the age of the king in the movie). At the time, Ying Zheng began to rule China, the seven states were already reduced to two larger states (Qin and Chu) which was later dominated by Qin when Ying Zheng was 22 years old. It is therefore impossible for the same king shown in the movie to be the king that united all the Chinese states, although the end-note is semantically correct.

The Director's Cut was 107:15 minutes, compared to the theatrical version at 96:23 minutes.
