Disney has released the full trailer for the live-action "Mulan" film. The adaptation of the 1998 animated movie hits theatres on March 27. It sees Chinese-American actress Liu Yifei play the leading role of Hua Mulan. The plot centres on Mulan disguising herself as a man to join the Imperial Chinese Army. The film's cast includes Donnie Yen, Jet Li and Jason Scott Lee. Actress Gong Li plays a new character, a powerful witch who serves as the main villain. The Huns also feature as antagonists, just like in the 1998 movie. Unlike the original, the live-action version of "Mulan" is not a musical. Eddie Murphy's dragon guardian, Mushu, also does not appear in the upcoming movie.
