Film with music from Mozart's opera of the same name

Idomeneus, King of Crete, one of the great heroes during the total destruction of the famous city of Troy was sailing back to his realm when a terrible storm broke loose near the city of Sidon. The storm was of such violence that in his fear Idomeneus made a solemn promise to Neptune, God of the Seas, to sacrifice the first person -no matter who it be- that he would meet on the shore if he and his people would only get there safely.
