Tracy Turnblad, a big girl with big hair and an even bigger heart, has only one passion--dancing. Her dream is to appear on "The Corny Collins Show," Baltimore's hippest dance party on TV. Tracy seems a natural fit for the show except for one not-so-little problem--she doesn't fit in. Her plus-sized figure has always set her apart from the cool crowd, which she is reminded of by her loving but overly protective plus-sized mother, Edna. That doesn't stop Tracy because if there is one thing that this girl knows, it's that she was born to dance. After wowing Corny Collins at her high school dance, Tracy wins a spot on his show and becomes an instant on-air sensation, much to the chagrin of the show's reigning princess, Amber Von Tussle, and her scheming mother, Velma, who runs television station WYZT. Even worse for Amber is the fact that it's not just the audience who loves the new girl in town; Amber's sweetheart, Link Larkin, seems to be smitten with Tracy's charms as well. This dance party gets personal as a bitter feud erupts between the girls as they compete for the coveted "Miss Teenage Hairspray" crown. At school, however, a short stint in detention and raised-eyebrows caused by the budding relationship between her best friend Penny Pingleton and Seaweed opens Tracy's eyes to a bigger issue than the latest dance craze or the coolest hairdo--racial inequality. Throwing caution to the wind, she leads a march with Motormouth Maybelle to fight for integration and winds up with an arrest warrant instead. Tracy is on the lam now and goes underground--literally--to her best friend Pennys basement. Has Tracy's luck finally run out? Will she miss the final dance-off against Amber and forfeit the title of "Miss Hairspray," or will she sing and dance her way out of trouble again? - skip ad - Genres: Musical/Performing Arts, Adaptation and Remake Running Time: 1 hr. 55 min.

That “Hairspray” is good-hearted is no surprise. Adam Shankman’s film, lovingly adapted from the Broadway musical, preserves the inclusive, celebratory spirit of John Waters’s 1988 movie, in which bigger-boned, darker-skinned and otherwise different folk take exuberant revenge on the bigots and the squares who conspire to keep them down. The surprise may be that this “Hairspray,” stuffed with shiny showstoppers, Kennedy-era Baltimore beehives and a heavily padded John Travolta in drag, is actually good.

Appropriately enough for a movie with such a democratic sensibility, there is plenty of credit to go around. Mr. Shankman, drawing on long experience as a choreographer, avoids the kind of vulgar overstatement that so often turns the joy of live musical theater into torment at the multiplex. The songs, by Marc Shaiman and Scott Wittman, are usually adequate, occasionally inspired and only rarely inane. And they are sung with impeccable diction and unimpeachable conviction by a lively young cast that includes Nikki Blonsky, Amanda Bynes, Zac Efron and the phenomenally talented Elijah Kelley.

Of course there are better-known, more-seasoned performers on hand as well, notably Queen Latifah, Michelle Pfeiffer, Christopher Walken and Mr. Travolta. But “Hairspray” is fundamentally a story about being young — about the triumph of youth culture, about the optimistic, possibly dated belief that the future will improve on the present — and its heart is very much with its teenage heroes and the fresh-faced actors who play them.

Ms. Blonsky, a ball of happy, mischievous energy, is Tracy Turnblad, a hefty Baltimore high school student whose dream is to dance with the city’s most telegenic teeny-boppers on “The Corny Collins Show.” Ms. Bynes plays Penny Pingleton, Tracy’s timid best friend, whose prim mother (Allison Janney) won’t even let Penny watch the show, much less appear on it. Mrs. Pingleton can scarcely imagine that her daughter will eventually fall for Seaweed (Mr. Kelley), part of a group of black kids whom Tracy befriends in the detention hall after school.

As Penny and Seaweed test the taboo against interracial romance, Tracy and Link Larkin (Mr. Efron), a “Corny Collins” dreamboat, take on the tyranny of slenderness. That “Hairspray” cheerfully conflates racial prejudice with fat-phobia is the measure of its guileless, deliberately simplified politics. Upholding both forms of discrimination is Velma Von Tussle (Ms. Pfeiffer), a television station executive who uses “The Corny Collins Show” — against the wishes of Corny (James Marsden) himself — as a way of maintaining the color line and promoting the celebrity of her blond, smiley daughter, Amber (Brittany Snow).

“Hairspray” does not seriously propose that Tracy and her new African-American friends face equivalent forms of injustice. But it does make the solidarity between them feel like an utterly natural, intuitive response to the meanness and arrogance of their common enemies. “Welcome to the ’60s,” Tracy sings to her mother, conjuring up the New Frontier hopefulness of that decade’s early years rather than the violence and paranoia of its denouement.

In freezing history at a moment of high possibility — a moment whose glorious popular culture encompasses “West Side Story” and the Twist, early Motown and Phil Spector’s Wall of Sound — “Hairspray” is at once knowingly corny and unabashedly utopian. On “The Corny Collins Show” Seaweed and his friends are relegated to a once-a-month Negro Day, presided over by Motormouth Maybelle (Queen Latifah). Tracy envisions a future when, as she puts it, “every day is Negro Day.”

What is missing from “Hairspray” is anything beyond the faintest whisper of camp. The original “Hairspray” may have been Mr. Waters’s most wholesome, least naughty film, but there was no containing the volcanic audacity of Divine, who created the role of Edna Turnblad. Divine, who was born Harris Glen Milstead and who died shortly after the first “Hairspray” was released, belonged to an era when drag performance still carried more than a touch of the louche and the dangerous, and was one of the artists who helped push it into the cultural mainstream.

Perhaps wisely Mr. Travolta does not try to duplicate the outsize, deliberately grotesque theatricality of Divine’s performance or to mimic the Mermanesque extravagance of Harvey Fierstein’s Broadway turn, choosing instead to tackle the role of Edna as an acting challenge. The odd result is that she becomes the most realistic, least stereotypical character in the film, and the only one who speaks in a recognizable (if not always convincing) Baltimore accent. (“Ahm tryna orn,” she complains when she’s trying to iron.)

A shy, unsophisticated, working-class woman, Edna is ashamed of her physical size even as she seems to hide inside it, as if seeking protection from the noise and indignity of the world outside. It is Tracy who pulls her out of her shell, and without entirely letting go of Edna’s timidity, Mr. Travolta explores the exhibitionistic and sensual sides of her personality.

Mr. Walken’s gallantry in the role of Edna’s devoted husband, Wilbur, is unforced and disarmingly sincere, and their duet, “(You’re) Timeless to Me,” is one of the film’s musical high points. Another is “Without Love,” in which the two young couples express their yearning with the help of some ingenious and amusing special effects.

There are, to be sure, less thrilling moments, and stretches in which the pacing falters. But the overall mood of “Hairspray” is so joyful, so full of unforced enthusiasm, that only the most ferocious cynic could resist it. It imagines a world where no one is an outsider and no one is a square, and invites everyone in. How can you refuse?

“Hairspray” is rated PG (Parental guidance suggested). It has some mildly naughty jokes and innuendo.
