Like any IMAX movie, Coral Reef Adventure is so vivid, vast, and colorful that you can't help but be astonished by its visual splendor. But this undersea exploration has a deeper, more serious agenda as well, warning its viewers that the natural magnificence of the world's most impressive coral reefs is, in most cases, a mere 30 years away from extinction due to the devastating effects of global (and oceanic) warming.

Believe it or not, an IMAX film can make the transition to video perfectly well. It might not be three stories tall, but Dolphins is still a lovely, larger-than-life exploration of these strangely intelligent creatures. Visit the Bahamas, Argentina, and beyond to see different varieties play and hunt. Pierce Brosnan's narration and Sting's music fill the water with sound and add counterpoint to the dolphin's shrill cries; the film is an overwhelming experience even in the living room.

For its 25th giant screen film, MacGillivray Freeman Films invites movie-going audiences to experience the mysterious world of the underground: the amazing world of caves. Premiering in select IMAX and other large-format theatres, Journey Into Amazing Caves is a visceral, suspenseful expedition with a new breed of scientists who boldly explore places once thought off-limits to human presence, let alone IMAX cameras.

Grand Canyon Adventure: River at Risk combines exhailarating river-rafting action on America's most iconic river, family fun and the grandeur of the Grand Canyon to tell an engaging story of how ordinary people can make a diffrence for our parched planet - one that is running out of clean, fresh water so fast that the U.N. estimates that 40 % of the world could face life - threatening shortages by the year 2050.

MacGillivray Freeman Films brings the thrill of flight and jet aircraft technology to the big screen with a film that balances the excitement of a Blue Angels air show with the science and history of flight.
