Theo Stevenson in the titular role and an all-star cast including Richard E Grant and Anjelica Houston in the new 3D feature film adaptation of Horrid Henry have now also been announced.

The previously announced cast includes Prunella Scales, Parminda Nagra, Noel Fielding, David Schneider, Jo Brand, Rebecca Front and Helen Lederer with Mat Horne and Siobhan Hayes as Henry's long-suffering parents.
In the movie Henry, who is the Lord High Majesty of the Purple Hand Gang, wages his ever-constant battle against the tyranny of adults, a number of whom seem to be out to get him.
"We have a great adult cast, brilliant kids and a hugely professional team. It's going to be fun!" said Vertigo Film producer Rupert Preston.
Kimberley Walsh, from Girls Aloud, will also make a cameo appearance as Henry's cousin Prissy Polly.
Shooting will take place in London for seven weeks and the film is set to be released next summer.
