After touring America as the nincompoop Kazakh journalist Borat, Sacha Baron Cohen tries again (strains, actually) as Brüno, the flamboyantly attired nincompoop Austrian journalist who comes to America seeking fame by every means necessary. That includes throwing his crotch at the camera and trying to shoot a sex video with an understandably terrified Ron Paul.
Like “Borat,’’ “Brüno’’ dares America to contradict itself, through a combination of documentary encounters and staged happenings in which many of the participants have little idea what’s going on. With luck, shrewd manipulation, and a beguiling performance from Cohen, “Borat’’ discovered a contemptuous jingoistic streak in good people. “Brüno’’ is a more confrontational affair: It wants to expose America’s homophobia, although calling this movie a work of activism is like calling Spam food.
