Chicken Little 2: Mission To Mars

Chicken Little 2: Mission To Mars was a planned sequel to the 2005 animated Disney film, Chicken Little.

Plot
The story would involve Chicken Little in the middle of a love triangle between his childhood sweetheart, Abby Mallard, and a very attractive newcomer, a French sheep named Raffaela. Being at a great disadvantage, Abby would go to great lengths to give herself a makeover.

Why It Was Cancelled

 * 1) The first film received mostly mixed to negative reviews from critics and audiences, so Disney decided not to make the sequel.
 * 2) When John Lasseter became Walt Disney Animation Studios' new chief creative officer, he called for all sequels and future sequels that DisneyToons had planned to be cancelled.
 * 3) A few of the cast members of the first film are now dead.

Result

 * 1) The sequel didn't come to surface nor was it announced for a DVD release.
 * 2) The video game Chicken Little: Ace in Action serves as an actual sequel to this film. Despite that, Chicken Little is a stand-alone film.
