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

 * The first film was panned from critics and audiences, so Disney decided not to make the sequel, and John Lasetter banned all future sequels after his appointment to CEO of Disney in 2006.

Result

 * The film was permanently cancelled.
 * Some of the elements of the sequel were used in the game Chicken Little: Ace In Action, and the game serves as a sequel to the film. Aside from the game, the first film is stand-alone.
