W Somerset Maugham who trained as a medical doctor before turning entirely to writing must have picked up the gist of the story from acquaintances. It leads us into the murky world of declining colonialism in China, in a tale of love, betrayal, atonement and ultimately personal redemption.
Naomi Watts adds the necessary reckless streak of the bored London flapper who, to escape her parents, marries the rather stiff scientist played by Norton, and then carries it on with someone else in Shanghai (Liev Schreiber).
Sumptuous landscapes introduce the film, long initial scenes sweeping over the luscious Chinese countryside and meals eaten in silence are the painted veil that finally lifts to show the true passion and love between Kitty and Walter.
It is some of Norton's best acting, and the movie benefits from a good script, and excellent actors giving their best, if at times understated. For once the music too is not overly intrusive - overall a very fine balance in a delicately acted film makes this very worthwhile watching; again and again.
