Movies: Ang Lee’s New Thriller

Ang Lee's "Lust, Caution" begins, in 1942 in Japanese-occupied Shanghai, on the day a long-simmering plot to assassinate a powerful Chinese collaborator is to occur. Wong Chai Chi (Tang Wei), a beautiful former student actress who has joined the resistance, has given away her innocence, her romantic dreams and years of her life to entrap the traitor, Mr. Yee (Tony Leung), the ruthless head of the secret service in Shanghai. Posing as a rich merchant's wife, she has become his mistress. It's a role she's played so deeply and so well she's begun to question her own identity, her loyalties, and what her true feelings are for the man she's about to lure to his death.

"Lust, Caution," which loops back in time to 1939 Hong Kong, unfolds on a large, opulently appointed canvas that recreates the decadence and paranoia of prerevolutionary Shanghai. An erotic, violent melodrama, filled with echoes of such Hitchcock movies as "Notorious" and "Suspicion," Lee's film is composed of one highly flammable ingredient after another. Why, then, doesn't it ever fully ignite? For all its hothouse passions and sometimes brutally explicit sex scenes, the storytelling seems curiously stolid, the style too movie-ish for its own good. Lee and screenwriters Wang Hui Ling and James Shamus have taken Eileen Chang's provocative short story and stretched it into a 157-minute epic. It's an intelligent adaptation, faithful to the themes and cruel ironies of the story, but the wrenching internal transformation at the heart of the tale—Wong's metamorphosis from idealistic student into a conflicted femme fatale enmeshed in a torrid, sadomasochistic affair—gets overwhelmed by the overproduced melodrama that surrounds it. There's a great, piercing story here, but too often you feel you're watching it through the wrong end of the telescope.

The cast gives it their all. The delicately beautiful Tang, a stage and television actress in mainland China making her film debut, is convincing as both naive schoolgirl and woman of the world, never overplaying her hand. She more than holds her own with the veteran star Leung, who makes the guarded, control-freak Mr. Yee a figure of complexity and even poignancy; he flexes his power with extra vehemence knowing, deep down, he's just a puppet to his Japanese masters. Lee, perhaps thinking of Hitchcock's "Torn Curtain," with its famous illustration of how hard it is to kill someone, stages an unforgettable variation on the theme: the brutal, messy, protracted murder of an informer by the inexperienced, young resistance team. It's certainly not the only striking, explosive moment in "Lust, Caution." But you wish there were more of them.
