Writing In September 2001, after the release of ''
The Emperor's New Groove, director Mark Dindal and producer Randy Fullmer began to work on their next project for Disney, and came up with the idea for Chicken Little'', with its title character envisioned as a paranoid female chicken with the voice of
Holly Hunter that went to summer camp to reduce her anxiety, as well as repair her relationship with her father. At the summer camp, she would uncover a nefarious plot that her camp counselor, who was to be voiced by
Penn Jillette, was planning against her hometown. "I have two daughters, so I immediately went to a father/daughter story," Dindal said. Dindal would later pitch his idea to former Disney Chairman and CEO
Michael Eisner who demanded that Chicken Little be changed into a male because as Dindal recalled, "if you're a boy and you're short, you get picked on." However, Dindal later clarified that the decision was made, in part, due to market research stating, "I remember being told, 'Girls will go see a movie with a boy protagonist but boys won't see a movie with a girl protagonist, [...] That was the wisdom at the time, until
Frozen comes out and makes $1 billion." During the rewriting process, Dindal, along with three credited writers and nine others, threw out twenty-five scenes to improve the character development and add more emotional resonance with the parent-child relationship. Dindal stated that "It took us about 2½ years to pretty much get back to where we started... But in the course of that, the story got stronger, more emotional, and Amazing, too." Against forty actors competing for the title role,
Zach Braff auditioned. Dindal noted he "pitched his voice slightly to sound like a junior high kid. Right there, that was really unique — and then he had such great energy." In April 2002,
Variety reported that
Sean Hayes was to voice a character named the Ugly Duckling, but the character was rewritten into a female. Now conceived as Abby Mallard,
Jamie Donnelly,
Jamie Lee Curtis,
Sarah Jessica Parker,
Jodie Foster,
Laura Dern,
Helen Hunt,
Geena Davis, and
Madonna were considered, but
Joan Cusack (who had previously voiced
Jessie in
Toy Story 2) won the role for her natural comedy. In December 2003, it was announced Braff and Cusack were cast, along with other cast members including
Steve Zahn as Runt of the Litter, Dan Molina as Fish Out of Water,
Amy Sedaris as Foxy Loxy,
Don Knotts as Turkey Lurkey,
Katie Finneran as Goosey Loosey, and
Garry Marshall as Buck Cluck. Halfway through production, however, Finneran ultimately left the project and was replaced by Disney storyboard artist
Mark Walton. Marshall was asked to provide a voice for
Kingdom of the Sun, which was re-conceived into ''
The Emperor's New Groove'' and directed by Dindal, but was removed from the project for being "too
New York". When he was approached to provide the voice for Buck Cluck, Marshall claimed "I said I don't do voices. You want a chicken that talks like me, fine. So they hired me and they didn't fire me, and it was like a closure on animation.". Before Marshall was cast,
James Earl Jones,
Bill Murray,
Stephen Colbert,
Christian Slater,
Martin Sheen,
Peter Falk,
Dennis Hopper,
James Woods,
Dan Aykroyd,
Mick Jagger, and
Willem Dafoe were previously considered for the role of Buck Cluck. Australian comedian
Mark Mitchell was hired to dub the voice of Buck Cluck for the Australian release of the film, as a decision by Disney to get a national celebrity to publicize the film. Similarly, before
Steve Zahn was cast as Runt of the Litter,
Danny Cooksey,
Jim Carrey,
Jeff Bennett,
Nicolas Cage,
Brendan Fraser,
Brad Garrett, and
John Goodman were previously considered for the role. This also marked the final film appearance of Knotts during his lifetime.
Animation To visualize this story, Disney selected 50 percent of its 2D animation staff to put them in a CGI animation team, and placed them through a rigorous eighteen-month training program with
George Lucas'
Industrial Light and Magic, which included an introductory to
Alias's
Maya that would serve as the main 3D animation software used on the project. This was due to Disney CEO
Michael Eisner announcing that the studio would move to computer animation in response to a downturn caused by rising competition from
Pixar and
DreamWorks Animation computer animated features, as well as the unsatisfactory box office performances of ''The Emperor's New Groove
, Atlantis: The Lost Empire
, Treasure Planet (2002), and Home on the Range (2004). As some of the animators had worked on Dinosaur'' (2000), which used live-action backgrounds, the animation team took inspiration for its staging, coloring, and theatrical lighting from
Mary Blair's background designs featured in
Alice in Wonderland (1951) and
Peter Pan (1953). For the aesthetics in the background designs, the background layout artists sparingly use digital
matte paintings to render out the naturalistic elements, including the trees and the baseball diamond, but they were retouched using
Adobe Photoshop as background cards featured in the film. Under visual effects supervisor Steve Goldberg who spearheaded the department, the Maya software included the software program "Shelf Control" that provided an outline of characters that can be viewed on-screen and provided a direct link to the controls for specific autonomy, as well as new electronic tablet screens were produced that allowed for the artists to draw digital sketches of the characters to rough out their movements, which was then transferred to the 3D characters. All of the characters were constructed using geometric polygons. For the title character, there were approximately fourteen to fifteen character designs before settling the design composed of an ovular egghead shape with oversized glasses. The final character was constructed of 5,600 polygons, 700 muscles, and more than 76,000 individual feathers, of which 55,000 are placed on his head. Following the casting of Braff, supervising animator Jason Ryan adapted Braff's facial features during recording sessions to better combine the dorkiness and adorability the filmmakers desired. "He's got this really appealing face and eye expressions," Ryan said, adding that he was amazed by Braff's natural vocal abilities. Next, the animators would utilize the software program "Chicken Wire", where digital wire deformers were provided for the animators to manipulate the basic geometric shapes to get their desired facial features. Lastly, a software development team constructed XGen, a computer software program for grooming fur, feathers, and generating leaves. ==Release==
