Desc: Chasing Walrus (With A Stubborn Photographer): Directed by Simon Stanford. When a film team travel to Greenland to film walrus underwater, it feels like an exciting but perfectly normal assignment. But a pack of hungry polar bears have different ideas. With the ice melted, and the walrus no-where to be seen, filmmakers Simon Stanford and Göran Ehlmé find themselves at the mercy of these arctic predators-fighting for survival in a habitat on the brink of collapse.
