The total crew numbered 457. Due to the length of the production, Aardman had to use a special blend of Plasticine for the more expressive features of the film s models. To achieve the correct hue, the Plasticine is mixed in a converted chewing gum machine. The first model of each character the bodies of which comprised of foam latext constructed around a steel armature cost around 10,000. Each of the chickens in the film had dozens of different mouths, shaped to vocalise each letter of the alphabet, as well as to convey emotion.
Chickens have cannibalistic tendencies.
The human characters in Chicken Run also wear fabric clothes. Mrs Tweedy s dress was wired stiff to allow it to be animated, and took one person three weeks to complete. Suffice to say, the name was shortened upon legal advice. Chickens have hollow bones, and are able to breath through them. There are 24 individual poses per second of film in Chicken Run.
