Set inside the mind of 11 - year - old Riley, where anthropomorphized emotions Joy, Sadness, Anger, Fear, and Disgust run the show and memories are downloaded to glowing orbs, the Pixar impresario has created
a vivid fictional world that rivals WALL - E in its inventiveness and lush visual landscape.
With the help of a
fictional guide dubbed John Lubbock, modeled after a Victorian naturalist who wrote a popular book called Prehistoric Times, Mithen embarks on a
vivid tour of the warming
world as it emerged from the last ice age.
