Comments: 70mm documentary film released in 2003 to IMAX theaters. It is narrated by Academy Award-nominated actor Liam Neeson and directed by veteran IMAX filmmaker Greg MacGillivray.

Summary: Embarking on a 10-month expedition through the islands of the South Pacific, husband and wife underwater photography-duo Michele and Howard Hall explore the declining reefs and failing health of the world's oceans. From Australia's Great Barrier Reef, to a friend's coral reef-sustained village in Fiji, the diving expeditions show a range of coral reefs, from flourishing ones filled with unusual and exotic inhabitants, to vast stretches of bleached coral decline which prompted the Hall's activism. Along their journey, scientists working to understand and save the reefs meet with the Hall's.

Jean-Michel Cousteau, son of the famed oceanographer Jacques Cousteau, also makes an appearance.

This documentary film is the third oceanic, ecologically-themed IMAX production from director MacGillivray, after The Living Sea and Dolphins. Crosby Stills & Nash contribute to the film's soundtrack. The Giant Screen Theater Association named it the best film achievement of 2003.
