It's not just that Marlon and Shawn Wayans get to play the eponymous white chicks in this latest laffer from the three Wayans Brothers. The two must convince as spoiled young Hamptons high-society hotties (think the Hilton girls) as they go undercover in full makeover to thwart a kidnapping in the midst of benefit season. Convince they do, no small thanks to make-up wizards Greg Cannom and Keith Vanderlaan, who provide the brothers with the prosthetic devices that turn them into giggly, bitchy, pampered social climbers, complete with publicist, loyal crew, horny suitors, and take-no-prisoners ambitions to land on the cover of Hamptons magazine and rule the social scene. Filmgoers with a low tolerance for silliness who give high marks to logic had best find other beaches to comb. But for all others, White Chicks delivers like a richly packed goody bag.

The story kicks off fast and funny with bumbling FBI agents Marcus and Kevin Copeland (Marlon and Shawn Wayans) in disguise as grocers in Spanish Harlem awaiting a drug delivery, and botching the assignment. Their angry boss demotes them, giving the humiliated agents the job of accompanying spoiled Beverly Hills socialite sisters Brittany and Tiffany Wilson (Maitland Ward and Anne Dudek) to the posh Hamptons resort for the benefit-filled Labor Day holiday weekend, where the obnoxious young women expect to emerge the reigning darlings of high society.

The agents even bungle this mission by causing a car accident that leaves cuts on the Wilson sisters' faces, a situation that forces the pampered pair to retreat back to Manhattan. Literally within a few screen minutes, the Copelands cover up this latest screw-up by engaging the services of an FBI makeover whiz who turns them into facsimiles of the Wilsons.

It doesn't require genius to guess that the bogus Wilsons conquer the Hamptons, but not without a bunch of close and hilarious calls. Director Keenen Ivory Wayans, by way of the highly serviceable script, puts the 'girls' through a number of familiar hoops: Marcus and Kevin in disguise--along with their posse of giggly gals--must do shopping (and dressing rooms), receptions, a charity auction, nightclubbing, romantic dinners with suitors, a slumber party, a fashion show on a catwalk that goes insanely feral, etc.--situations that amount to hilarious set-pieces in which the Wayanses deliciously show their stuff as chicks.

Of course, the apocryphal Wilson sisters, as popular as they are, must deal with adversaries: a rival posse of high-society wannabes led by Heather and Megan Vandergeld (Jaime King and Brittany Daniel), the daughters of Hamptons society staple Warren Vandergeld (John Heard), who may actually be (though we're not saying) a sleazy, no-good bastard who is object of the FBI hunt.

Of course, White Chicks is loaded with risqu and tasteless scatological humor, with fart jokes making the most noise, but there's nothing that pushes the material beyond its benign rating--although ultra-beefy sports-star millionaire Darnell Johnson's (Terry Crews) obsessive and riotous courting of Marcus/Tiffany comes deliciously close to pushing the envelope. But the film also provides sweet and warm pockets for romance involving Marcus' distraught wife Gina (Faune Chambers) and Kevin's romance with Hamptons-based investigative reporter turned puff-piece purveyor Denise Porter (Rochelle Aytes).

The Wayanses look great as gals and the film itself looks fine. Vancouver suffices as a substitute for the Hamptons, although those familiar with the turf will squabble. But there's no denying that the filmmakers nail the young, squealy denizens of certain Hamptons summer social events. Filmgoers will enjoy their own insiders' look at the excess and at a fraction of the price.
