The movie was originally released in France on March 28, 2018 as Blue. The movie was originally set for an April 2018 theatrical release under the title Dolphins with narration by Owen Wilson, which was scrapped. It is now set for release on Disney+ and narrated by Natalie Portman.
Created with Disneynature’s signature storytelling style, the film introduces Echo, a young Pacific bottlenose dolphin who can’t quite decide if it’s time to grow up and take on new responsibilities. Dolphin society is tricky, and the coral reef that Echo and his family call home depends on all of its inhabitants to keep it healthy. But Echo has a tough time resisting the many adventures the ocean has to offer.
