The trainer of Flipper made a documentary on assassination of dolphins in Japan, called "The Cove". Dolphins are hunted for meat or to make them prisoners in aquariums. The director realized that having dolphins in captivity was a mistake, after one of the dolphins portraying Flipper commited suicide.

The mayor of Taiji, Kazutaka Sangen, protested at the film's Oscar win.
"I think it is regrettable that the film presents as fact material that is not backed up by scientific proof," he said in a statement reported by Reuters news agency.
He said that the hunt was legal in Japan and called for respect for the traditions of different cultures.
