Trust the Italians for GREAT drama! The love theme from the 1988 movie "Cinema Paradiso," is perfect and GUARANTEED to make them cry. Over-sentimental but that's what you want. There's even a weeping violin at the end.

And here is the theme music from the same film as conducted by Ennio Moricone himself. The same music was used at the 2006 Oscars tribute to Morricone himself for his lifetime achievement award.
