Reviewed - Borat: Cultural learnings of America for make benefit glorious nation of Kazakhstan: Make good joke, yes? Borat is an uproarious satire of middle American mores and values as seen through the eyes of a dimwitted foreigner, writes Michael Dwyer.

JAM-packed with visual and verbal gags from start to finish, and entirely unencumbered by such incidentals as good taste, this uproarious, politically incorrect farce stars Sacha Baron Cohen in an impishly oversized performance as Borat Sagdiyev, the Kazakhstan TV reporter he created on TV in Da Ali G Show. The production values are as cheap and cheerful as in Cohen's earlier cinema vehicle, Ali G Indahouse, but Borat is altogether spikier and funnier.

A brisk prelude set on his home turf establishes Borat as a naive, opportunistic and unrepentantly sexist fellow, who actually boasts that his sister is "number four prostitute in all of country". Landing some state funding, he and his obese, much-suffering producer (Ken Davitian) embark on a fact-finding documentary about the USA.

Borat's multiple misadventures across the Atlantic involve kissing startled men on both cheeks, shocking representatives of the Veteran Feminists of America, enraging a rodeo audience by singing the lyrics of the Kazak national anthem to the tune of The Star-Spangled Banner, and appalling a southern family when he brings a prostitute as his dinner guest - not because of her profession, but because she's black.

Directed by Larry Charles at a frantic pace that never slackens, the movie gleefully seizes on every opportunity to poke fun at American mores. To make his points about bigotry in a film with something to offend everyone without a sense of humour, Cohen, who is Jewish, peppers the picture with casually anti-Semitic remarks.

The narrative, such as it is, involves Borat discovering a Baywatch repeat on late-night TV and resolving to seek out and marry Pamela Anderson, who sportingly plays herself. It reduced me to tears - of uncontrollable laughter.
