Eden Leisure yesterday launched Dolphins - the 24th Imax Theatre film from MacGillivray Freeman Films, producers of the box-office hit Everest.

The film will be open to the public from April 30.

From the dazzling coral reefs of the Bahamas to the windswept seas of Patagonia, Dolphins takes audiences under the water's surface for a romp with inquisitive Atlantic spotted dolphins, acrobatic dusky dolphins and the familiar bottle nose dolphin of Flipper fame.

Studying, and filming elusive, fast-moving animals in the ocean environment is a difficult task but in Dolphins viewers will follow young marine biologist Kathleen Dudzinski and her two colleagues, mentor Bernd Würsig and Alejandro Acevedo-Gutierrez, as they research the communication of wild dolphins with innovative scientific methods and interesting technology.

Dolphins is narrated by Pierce Brosnan and features the music of Grammy-award winning artist Sting and is produced and distributed by MacGillivray Freeman Films in association with the National Wildlife Federation, the nation's largest member-supported conservation group.
