Boy on a dolphin

"Italian goddess Sophia Loren made her American film debut in this adventure yarn set upon the Greek island of Hydra. There in a seaside village the beautiful Phaedra, a sponge diver, finds a breath-taking gold statue of a boy riding a dolphin. Her slimy and crooked boyfriend wants to sell it to an unscrupulous and wealthy art collector, but Phaedra wants to hand it over to an American anthropologist, Jim Calder, who would return it to the Greek government, so it could be displayed in a prominent Greek museum"--Container.
