Vertigo Films and Novel Entertainment have been hard at work on Horrid Henry: The Movie over the past few months. Slowly but surely, the pieces are falling into place, as the production ramps up for the 2011 release. The Nick Moore directed, 3D film already has a number of stars in the cast, including Anjelica Huston, Richard E. Grant, Rebecca Front, Parminder Nagra, Noel Fielding, Mathew Horne, Prunella Scales, and Jo Brand. Now, the reports indicate Kimberley Walsh will make a cameo appearance as Prissy Polly, Henry’s cousin. Based on Francesca Simon’s Horrid Henry books, Horrid Henry: The Movie will focus on Henry and The Purple Hand Gang in their ever constant battle against the tyranny of adults.
