Arthur and The Invisibles (U)

Half live-action film, half digital cartoon, Arthur and The Invisibles stars Freddie Highmore as a resourceful 10-year-old who lives with his grandmother, Mia Farrow, in her Connecticut farmhouse. The property will be bulldozed by a nasty developer unless Arthur can find the rubies which his grandfather has hidden in the grounds. But his grandfather has disappeared, so Arthur has to get some African tribesmen to shrink him down to microscopic size, enabling him to team up with the pixies who live in the back garden.

With me so far? It's a knotty tangle of characters and concepts from Star Wars, Arthurian myth and Alice In Wonderland. But once it gets going, there's enough kinetic adventure to thrill young children, as Arthur battles mosquitoes and drives a wind-up toy car. Adults can listen out for the voices of Robert DeNiro, Harvey Keitel, David Bowie and Madonna.
