Maybe Woody Allen has a deal with travel agents. His Midnight in Paris made me want to visit that city (albeit in the 1920s - a problem).
And his upcoming To Rome With Love will no doubt get me to want to go to that city (albeit to also run into Ellen Page, Penelope Cruz, Greta Gerwig, Carol Alt... Woody knows how to pick them).
Great cast, beautiful city and photography. Hopefully, another good film too.
