The Professional‘s Luc Besson has made a fair share of artfully bad movies. Arthur and the Invisibles — half-live-action, half-CG kid’s adventure — is (by a hair) more bad-bad, like The Fifth Element, than good-bad, like The Big Blue. Freddie Highmore is a kid who, to save his granny’s farm, must turn into a cartoon and enter the tiny world of the Minimoys. There he engages in some derivative derring-do and romances a princess voiced by Madonna. She and Highmore are officially the weirdest voice-over pairing of all time.
