Moment By Moment - A personal diary and updates

I have sent SMSs with clues for the real title of the film to a select few, who I thought were cluey enough (pardon the pun) to work things out. Alas, I underestimated my encryption powers. To make it easier, thought of posting all the clues collectively

BTW
It is a two word title
On offer a bottle of champagne to the one who gets the closest.

The Clues:
A compass won’t help you as much as a key
People come to watch
The eyes need it
Mallet and chisel build it in vaulted stones

Bon chance!
