‘‘The Cove,’’ a U.S. film about a controversial annual dolphin hunt at a Japanese town, won the best documentary feature at the 82nd Annual Academy Awards ceremony Sunday in Los Angeles.

Directed by Louie Psihoyos, one of the world’s most prominent still photographers, the film depicts, partly through the use of hidden cameras and microphones, the capture of dolphins by local fishermen in the whaling town of Taiji, Wakayama Prefecture.

If you haven’t seen it – do so now. This is a film which must be seen and talked about.
