The Hollywood Reporter reports that Madonna will voice the role of Princess Selenia, a character who travels with Arthur to a mysterious forbidden city where an evil being dwells, in the CG-animated feature film Arthur. Directed by Luc Besson (The Messenger: The Story of Joan of Arc) and produced by his Europa Corp, Arthur is adapted from a series of children’s books written by Besson, who also wrote the screenplay for the movie. Ten-year-old Arthur, in a bid to save his grandfather’s house from developers, goes in search of treasure hidden in the land of the Minimoys, a tiny people living in harmony with nature. Scheduled for a 2006 release, the $80 million Arthur will include some live-action sequences, with the 3-D animation being crafted by French specialist Buf Compagnie.
