Throughout Julia Donaldson’s two stories, The Gruffalo and The Gruffalo Child, the role of the Mouse is that of a trickster who somehow find himself avoiding danger. Creating what he thinks is a creature of pure fabrication, known as “The Gruffalo,” he eventually finds such a beast exists. In two different tales that see Gruffalo and Mouse crossing paths, James Corden’s vocal talents brought that character to life in the Oscar-nominated animated short, as well as its sequel, among a cast that also included Helena Bonham Carter, Tom Wilkinson and the late John Hurt.
