“I don’t have any specific destination in mind—I’m just gonna go until I run out of places to go,” says the lovelorn New Yorker played by singer Norah Jones in this aimless, episodic road movie. It marks the U.S. debut of Hong Kong director Wong Kar-wai (In the Mood for Love), and though it’s beautifully shot (and characteristically drenched in red orange light), the characters gently bump each other away, like slow-rolling billiard balls. Dumped by her boyfriend, Jones shares late-night colloquies with sweetie-pie Jude Law in his picturesque diner, then hits the road; waiting tables in Memphis she crosses paths with a troubled cop (David Strathairn) and his wife (Rachel Weisz), and in Las Vegas she hooks up with a brassy young gambler (Natalie Portman). In these dusty American settings, the wistful melancholy of Wong’s earlier movies seems fairly contrived. PG-13, 90 min.
