“When the Emperor of China issues a decree that one man per family must serve in the Imperial Army to defend the country from Northern invaders, Hua Mulan, the eldest daughter of an honored warrior, steps in to take the place of her ailing father. Masquerading as a man, Hua Jun, she is tested every step of the way and must harness her inner-strength and embrace her true potential. It is an epic journey that will transform her into an honored warrior and earn her the respect of a grateful nation…and a proud father. “Mulan” features a celebrated international cast that includes: Yifei Liu as Mulan; Donnie Yen as Commander Tung; Jason Scott Lee as Böri Khan; Yoson An as Cheng Honghui; with Gong Li as Xianniang and Jet Li as the Emperor. The film is directed by Niki Caro from a screenplay by Rick Jaffa & Amanda Silver and Elizabeth Martin & Lauren Hynek based on the narrative poem “The Ballad of Mulan.””
Given the nature of the film, I wonder if they did all the dialogue in Chinese as well for the China market. It would be kind of weird to see a film set in China sub-titled in Chinese speaking in English (or dubbed in Chinese). From the trailer, it looks to be somewhat fantastical, like Crouching Tiger, Hidden Dragon.
