For which film did Manos Hatzidakis win an Academy Award for Best Music, Original Song?

Melina Mercouri (later a politician) was sensational in this 1960 movie, as was that great song and the rest of the soundtrack. These were no Greeks to beware of. And then of course we had Maria Callas, Katzanzakis and a few more, not to mention the myriad ancients.

Player #23904119, I think Melina Mercouri was a bad actress. She was a good politician though.

I love Greek Mythology and this game, rarely goes there!! Why is that, I wonder.
