Blue Whales: Return of the Giants 3D will entertain audiences of all ages and transform our understanding of these iconic creatures. The film follows two scientific expeditions: one, a high-risk mission to find a missing population of blue whales, not seen in 50 years; and the other, to join Diane Gendron, the “Blue Whale Whisperer,” in Mexico’s Gulf of California, where she and her team explore the important role these remarkable animals play in the health of our oceans.
