Angelina Jolie and Brad Pitt surprised fans in Panama City on Friday, visiting a souvenir shop, colonial neighborhood and the Panama Canal, where one resident yelled, "Are you Brad Pitt?" The actor smiled and said: "Sometimes." The Hollywood couple flew to Panama on Thursday, taking a side trip from their holiday stay in Costa Rica. Besides touring the capital, where they shopped for souvenirs and walked around a colonial neighborhood, Pitt and Jolie visited a former U.S. military base and the construction site of Panama's new Biodiversity Museum, designed by Frank Gehry, at the entrance of the canal in the town of Amador.
