Bruno

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.
