Zhang Yimou is one of the world’s greatest filmmakers. He’s probably best known for directing the opening ceremonies of the Beijing Olympics, but his films—“Hero,” “House of the Flying Daggers” and “Raise the Red Lantern,” among many others—are essential viewing. His latest effort, which re-teams him with longtime muse, Gong Li, is some heavy duty melodrama in the best sense of the word. “Coming Home” takes place during the Cultural Revolution in China, with Gong playing the wife of a controversial professor who was jailed by the government. Years later, when he’s released, his wife doesn’t remember him as her husband and from time to time even thinks he may be an official she slept with to stave off her husband’s execution. Heavy stuff, but this is Zhang Yimou, who is more than capable of turning the story into a stunning discovery.
