Based on a book, this adventure follows Arthur (Freddie Highmore) as he journeys in his own backyard to save his home from greedy land developers. When his grandfather disappears, Freddie follows a series of clues that lead him to the land of the Minimoys (aka the Invisibles). Arthur's entrance into their realm takes the film from live-action to computer animation, changing Arthur from a 10-year-old boy into one of the Minimoys. The elf-like people he encounters are so tiny that insects dwarf them. Their warrior princess (voiced by Madonna) is ready to ascend the throne of the tiny kingdom. But first she and Arthur must join forces to outwit the evil Malthazar (voiced by David Bowie), who is intent on destroying the kindhearted race.
