Wallace and Gromit are the main characters in a series of 4 British animated short films, a series of 10 short animated sequences, and a feature-length film by Nick Park of Aardman Animations. All the characters were made from molded Plasticine modeling clay on metal armatures, and filmed with stop-motion clay animation. Wallace is an absent-minded inventor, cheese enthusiast, and companion to the dog, Gromit, who appears to be rather more intelligent than his master. Wallace is voiced by veteran actor Peter Sallis. Gromit remains silent and has no visible mouth, communicating only through facial expressions and body language.
