Twilight fan Malicious Mandy has a great trip report from Montepulciano, where she tries to gather some intel on the filming locations and such before New Moon begins filming in Montepulciano, Italy later this month.

Obviously the Piazza Grande will be used. That will be the busy square that Bella runs through just as the clock (conveniently on the tower) strikes noon. There are two alleys on either side of the main building, and both are fairly atmospheric, but I’m not convinced that they’ll be the ones used in the film. [....] The other building that they are supposedly using (none of this is confirmed, I’m just going on Montepulciano’s tourism board), is the Palazzo Selimbini. It’s about a ten minute walk straight downhill from the Piazza Grande.

Check out the rest of her report
