A man walks past an advertisement of a local movie displayed outside a cinema in Rawalpindi, Pakistan. Pakistan stars in "Zero Dark Thirty," from early scenes at a detention site to the dramatic closing minutes as Navy SEALs assault the hideout of bin Laden. But the Academy Award-nominated film about the hunt for the al-Qaida leader has sparked a controversy here about its portrayal of the country, and it will likely not be shown on the local big screen anytime soon. Partly, the film taps into national discomfort that bin Laden was found to be living for years near Pakistan's equivalent of West Point, and anger over the US decision to enter its airspace and raid the compound without giving advance notice.—Photo by AP
