In 2005 Pascal Thomas adapted an Agatha Christie story for the screen, signed up Catherine Frot and Andre Dussollier for the leads and enjoyed the minor success which prompted him to do it again ergo Zero Hour. In my case top-billed Danielle Darrieux - still acting in her ninety first year - was all the inducement I needed to get it up at the box office and the fact that Thomas has made another competent film is a bonus. If you like movies in which the actors wear timeless, well-cut clothes, move in a well-appointed château with a seascape thrown in for good measure and behave in obligatory mysterious ways so that an eventual murder has been long anticipated then you won't be disappointed. Chiara Mastroianni, looking more like her father every day is also on hand to remind us what we lost when her father died and if she bears only a passing resemblance to her mother that's not so important because mum Catherine Deneuve is still very much with us. It's doubtful if Chiara will ever achieve the iconic status of her parents but she gets acting jobs because casting directors and producers know she can deliver rather than because of her genes. An enjoyable romp.
