Beautiful photography and atmospherics capture Florence and environs. Technically very well-made and expensive-looking production.
Kristin Scott Thomas is perfect for the role and gives a terrific performance. The other cast members just seem to be giving their "standard" performance (Bancroft's standard mature woman routine that no one does better but she has done it since "The Hindenburg"). Ditto James Fox and the others.
The late William Holden could not have accomplished what Sean Penn did in "Mystic River", for which Penn gained a well deserved Oscar award. Conversely, Penn cannot play the Holden-type role in "Up at the Villa". Bad case of miscasting with flat results by Penn. No chemistry with Kristin Scott Thomas at all.
How can you make a dull, uninspiring film in an exotic setting with great actors in a highly charged brink-of-war scenario? SEEMS IMPOSSIBLE BUT THE FILMMAKER HERE HAS DONE IT!
