Arthur and the Invisibles (2006)

With his parents away on business and his grandfather missing, the only stability Arthur has in his life is his loving but eccentric grandmother and the house they share. But even that's in jeopardy thanks to the predatory interest of a land developer. Arthur goes off in search of a mythical treasure in a last ditch bid to save his grandfather's home, and he finds himself entering a land occupied by the finger-sized Minimoys. With his new friend at his side, Arthur sets off in search of the treasure his grandfather allegedly hid away. He might find romance along the way as well.

Arthur and the Invisibles is an adventure movie featuring Freddie Highmore and directed by Luc Besson.
