The Cove is a 2009 documentary that explores and questions dolphin hunting practices in Japan, especially the annual dolphin capture and slaughter in a cove in the Japanese fishing town of Taiji. It follows Ric O'Barry and people from the Oceanic Preservation Society as they conduct a covert operation to deploy hidden video cameras in the cove in order to film the slaughter. The film won the Academy Award for Best Documentary Feature in 2010.
After training the dolphins for the Flipper TV series in the 1960s, O'Barry became concerned of the side effect of the show's popularity, as dolphins became an increasing attraction at water parks and more and more where captured and used in shows and swim-with-the-dolphins attractions. He therefore started being an activist for freeing captive dolphins and stopping dolphin hunting. The Cove explains how dolphins are highly intelligent animals that don't belong in captivity and how dolphin hunting should be banned, as dolphin meat contains dangerously high levels of mercury anyway.
