Horrid Henry: The Movie (U)

Starring: Richard E Grant, Theo Stevenson, Anjelica Huston

This unutterably feeble-minded and unfunny movie is based on a series of children's books (by Francesca Simon) that are apparently the most successful in the UK after Harry Potter.

I have no idea how this could have happened. It's not just that it seems made for 12-year-old children with Attention Deficit Disorder and a tin ear for comedy; it seems to have been made by them, too. Theo Stevenson plays the disobliging eponym, his early attempts at gangsta-rap a warning that this might well try one's patience. He's joined by a motley of British faces - Richard E Grant, Mathew Horne, Parminder Nagra – and an American, Anjelica Huston, playing a Scottish teacher named Miss Battle-Axe. Do you get the picture? If not, keep it that way.
