To-the-manor-born Maxine (Jacinda Barrett) finds herself in strange surroundings when her Yale boyfriend, Gogol (Kal Penn), takes her home to meet his traditional Indian parents in "The Namesake."

The spices may be exotic, but the basic ingredients are universally familiar.

And the resulting cinematic dish -- director Mira Nair's "The Namesake" -- is rich and complex, utterly delicious and undeniably satisfying.

Based on the Pulitzer Prize-winning novel by Jhumpa Lahiri, "The Namesake" focuses on a family whose ties bind them not only to each other but to two countries and two cultures: India and America.

Inevitably, those generations -- and cultures -- clash.

But, happily, "The Namesake" doesn't bog down in cheap melodramatics.

Like its director, Indian-born, New York-based Mira Nair, "The Namesake" ultimately embraces, and celebrates, its dual loyalties.

Unavoidably, there's a lot of tsuris, as my Yiddische mama would describe all the heartache faced by the Ganguli family on their odyssey from hot, eye-poppingly colorful Calcutta to snowy, somber New York.

When the journey begins, Ashoke and Ashima (played, respectively, by Bollywood veterans Irfan Khan and Tabu) hardly know each other. After all, theirs is an arranged marriage, but the prospect of life in America -- and a chance to escape her smothery, tradition-bound family -- convinces Ashima to accompany the studious Ashoke.

Of course, life in the States has its challenges. Some of the differences -- round-the-clock hot water and gas for the stove, for example -- are easy to get used to.

Others, however, require greater adjustment, as when the couple's son Gogol (Kal Penn) -- "The Namesake's" title character, named for Ashoke's favorite writer, 19th-century Russian Nikolai Gogol -- grows up to be a thoroughly all-American guy devoted to sex and drugs and rock 'n' roll. And devoted not at all to his Indian heritage, judging by his choice of college girlfriend: Maxine (wispy, WASPy Jacinda Barrett), a Long Island princess with an impeccable bloodline and a prettily pouty reaction to his parents' old-fashioned ways.

Yet, those traditions prove harder to ignore than Gogol realizes -- especially when he falls for a free-spirited Bengali beauty (Zuleikha Robinson) and learns that cultural compatibility doesn't necessarily guarantee domestic bliss.

And what about his parents? Naturally, they only want him to be happy -- and they know better than to share their hard-earned wisdom. But never mind; he'll find out eventually. (Soon enough, they hope, to figure out that the cultural conflict he feels is all in his mind, not his heart.)

"The Namesake" reunites Nair with screenwriter Sooni Taraporevala, who also scripted the director's 1988 breakthrough "Salaam Bombay!" and her 1991 follow-up, "Mississippi Masala." And while there's no way to avoid compressing Lahiri's sprawling novel into a two-hour feature, Taraporevala retains its spirit and its overarching theme linking East and West.

All three Nair-Taraporevala collaborations display rare warmth and generosity of spirit, but "The Namesake" strikes its own profound notes, thanks in part to the movie's stirring combination of sight, sound and soul.

A distinctive visual stylist, Nair employs deft leitmotifs to underline the characters' connections, from recurring shots of bridges that span the movie's two worlds to more than one character trying on another's shoes, literally as well as figuratively walking in their footsteps. And Nitin Sawhney's insinuating musical score augments the movie's beguiling blend of exotic and homey elements.

Most of all, however, it's the characters themselves -- and the actors who embody them -- who breathe such palpable, powerful life into "The Namesake."

It's a pleasure to watch Kal Penn stretch beyond his breezy roles in such light-hearted, light-headed comedies as "Harold & Kumar Go to White Castle" and "Van Wilder 2: The Rise of Taj." In "The Namesake," we watch with equal amusement and annoyance as Gogol displays the sullen self-indulgence -- and total heedlessness -- of a young man convinced that he couldn't possibly learn anything from his parents.

Maybe Gogol's not paying much attention, but we are, thanks to the subtle and infinitely moving performances of both Khan and Tabu.

Khan (who played the title character in 2003's "The Warrior" and has come a long way since his first screen credit in "Salaam Bombay!") manages to capture Ashoke's gentle idealism and quiet dignity without transforming himself into a plaster god. Amazingly, Tabu's even better as Ashima, revealing a world of emotion and meaning through exquisitely controlled, often wordless expression.

As they face life's often outrageous slings and arrows, its bittersweet joys and poignant disappointments, "The Namesake" emerges as a triumphant example of the kind of movie in which "nothing happens" -- and yet everything happens. That is, everything we call life.
