From mysteriesofthegreatlakes.com:

The giant screen film, Mysteries of the Great Lakes, is as much a celebration of Earth’s greatest freshwater ecosystem as it is a rallying cry for protection. The story will take audiences on an inspiring voyage through these amazing inland seas. In the film, a few stops along the way highlight the stories of three key species - one each from water, air and land. The film also turns the camera on us, as humans - by touching on the human interface with the Lakes including the role of shipping to commerce, the use of the Great Lakes’ water by the millions of people who rely on it for life, and the general sense of well-being that people receive from simply being near these massive bodies of water.

The scenery and wildlife footage captured through the IMAX lens for Mysteries of the Great Lakes is spectacular, with some shots being unlike anything ever captured for this medium before. Filming took the production crews from beneath the waves of the Wolf River in Wisconsin - where thousands of lake sturgeon, the world’s largest freshwater fish, thrashed in the shallow rapids en route to their spawning grounds - into the skies to shoot aerial footage of all of the Great Lakes.

Thanks nasunto for the find! The film opens February 12, 2010 at Celebration! Cinema in Grand Rapids.
