The documentary film is directed by Louie Psihoyos and follows Ric O'Barry, a former dolphin trainer and few other animal activists who try to gain access to the secret cove in Taiji where the dolphins are killed. The film was pictured secretly using hidden cameras and underwater microphones. The Cove has won several prestigious awards including the Academy Award for best documentary in 82nd Annual Academy Awards, Golden Tomato Award from the critic website rottentomatoes.com and the U.S Audience Award at the Sundance Film Festival 2009.
The film received fierce opposition from some groups in Japan who consider dolphin hunting as part of their tradition. Initially it was screened at two venues in Japan but in 2010 several theaters in Japan started screening the film. The film was also screened at the Tokyo Film festival as a result of the protests by people. It has helped in creating awareness among the people of Japan of how dangerous dolphin meat can be for the health. As a result of the film, the local fishermen have now stopped killing the dolphins in cove and have moved offshore.
Based on the documentary, a new TV series will start on Animal Planet which has been titled 'Dolphin Warriors'. The series will star Ric O'Barry and address the issues regarding the present status of dolphin slaughtering in Taiji, Japan.
