Bears busting a move in the Canadian Rockies and a rascally raccoon family in Toronto are among the animals profiled in “Planet Earth II,” the followup to the massively popular 2006 TV series that won four Emmys. Debuting Saturday on BBC Earth, the visually arresting six-part series was filmed in 4K in 40 countries over a span of three and a half years, featuring exotic jungles, deserts, islands and grasslands.
