Holly Jones China’s unwitting creative phenom Yang Zhigang, known as Busifan, presents an imaginative, heartwarming and gleefully chaotic animated journey in his latest feature, “The Storm,” selected to screen in main competition at this year’s Annecy Festival. The auteur previously worked in telecommunications and never formally studied filmmaking, yet emerged as a self-taught cult figure on China’s animation circuit via its Flash scene in 2004 with “The Black Bird,” a seven-act episodic that craftily followed a wary warrior and his avian aide.
