Arthur and the Invisibles is a French/American part-animated, part-live action feature film adaptation of the 2002 children's book Arthur and the Minimoys, and the 2003 sequel Arthur and the Forbidden City, written by filmmaker Luc Besson, who also directed the film. In the year 1960, protagonist Arthur is living with his grandmother Daisy in a quiet farm house. His grandfather Archibald has recently gone missing and he sees little of his parents. Daisy entertains Arthur by reading stories of his grandfather's adventures in Africa, featuring the tall Bogo Matassalai and the minuscule Minimoys, of whom the latter now live in Archibald's garden, protecting a collection of rubies. Arthur becomes enamoured of Selenia, the princess of the Minimoys. When Daisy receives a two-day deadline to pay a large sum of money to a building developer named Ernest Davido, who plans to evict the two, Arthur looks for the rubies to pay off the debt, stumbling across various clues left by his missing grandfather.
