In efforts to shine a light on the disastrous effects of underwater noise pollution, Rachel McAdams is narrating “Sonic Sea”, a Discovery Channel film part of the Discovery Impact series. The documentary is premiering Thursday, May 19th at 9 PM ET/PT.

The 60-minute documentary travels beneath the ocean’s surface to uncover the impact industrial and military ocean noise has on whales and other marine life. Many life forms in the ocean depend on sound to mate, find food, raise their young, migrate and defend against predators. But when this symphony of life is disrupted the consequences are sometimes deadly.

“I was shocked by it and very emotional and surprised about how little I knew about what’s going on in our oceans. You don’t hear it, but it’s a whole cacophony down there.”, Adams said after having received the rough cut of the documentary from the filmmaker.

Compelled by the footage, the actress decided to lend her voice to the project, that in addition features renowned ocean experts Dr. Sylvia Earle, Dr. Paul Spong, Dr. Christopher Clark and Jean-Michel Cousteau as well as Grammy-Award winning musician, human rights and environmental activist Sting.


“Sonic Sea” premieres Thursday, May 19th at 9 PM ET/PT, exclusively on Discovery Channel.
