Arctic Tale [Blu-ray]

Stunning cinematography and two fun subjects, a polar bear and a walrus, mark this appealing nature study, which also offers an environmental message. Husband-and-wife co-directors Adam Ravetch and Sarah Robertson spent six years filming the project. Hip-hop superstar Queen Latifah provides a lively narration. One of the three screenwriters is Kristin Gore, daughter of former vice president Al Gore. The production is from National Geographic Films ("March of the Penguins.")
