From the flamboyant director of Priscilla, Queen of the Desert, this sublime adaptation of Noel Coward's tragic-comic play zings with dazzling wit and impeccable timing delivered by acting of the highest order. Who knew Jessica Biel could be so delicious as the American interloping fallen woman? Among the British stars, Colin Firth provides the counterpoint gravitas as a WWI surviving member of the "lost generation" who turns the tables on his insufferable wife (Kristin Scott Thomas) and besotted son. Easily one of the most entertaining movies of the past several years, it deserved the genuine spontaneous standing ovation at the world premiere screening I attended at the Toronto film festival. Scott Thomas is devastating in a totally different French-speaking role in "I've loved you for so long", for which she deserves an Oscar nomination. But see this for arch Brit humor at its finest.

• In the vintage Monte Carlo scene which opens the movie, when Larita first sees John both her and John's movements are slowed down while the rest of the cast play at 'normal' (i.e newsreel) speed. This was accomplished by filming the crowd, Larita, John, the background and the foreground mechanics separately against green screen and compositing them together at different speeds.
