Mulan III

Mulan 3 was a planned sequel to the 1998 film and the 2005 sequel Mulan II. It was planned for a 2007 release.

Plot
A few months after Mulan II, Mulan must help a Chinese maiden named Wei Hua to save her father Wu Takashi, who is imprisoned in Japan.

Why it was Cancelled

 * 1) Mulan II got extremely negative reviews.
 * 2) John Lasseter called off all future direct to DVD films after being appointed as head of Disney in 2006.
 * 3) The production was left unfinished.

Result

 * Mulan 3 was permanently cancelled.
 * This year (2020) Disney will release the remake of the first Mulan, but without singing (save for the songs performed by the Artists than the Cast) or Mushu. Instead, Phoenix would show up in place of Mushu.
