Pitt and Jolie visit the Panama Canal

PANAMA CITY, Panama - Angelina Jolie and Brad Pitt surprised fans in Panama City on Friday, visiting a souvenir shop, a colonial neighborhood and the Panama Canal.

One resident yelled, "Are you Brad Pitt?" The actor smiled and said: "Sometimes," according to the newspaper Panama America.

Besides touring the capital, where they shopped for souvenirs and walked around a colonial neighborhood, Pitt and Jolie on Thursday 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 Amador district.

The newspaper said Pitt, who has a love of architecture, and Jolie were considering investing in the $56 million project and buying land in Panama.

The museum, which will trace Panama's natural history, will include a botanical garden.

Publicists for Pitt and Jolie couldn't be reached for comment.

The couple, who arrived Thursday, were to return on Saturday to Costa Rica, to celebrate the New Year at a beachfront resort where room prices range into the thousands of dollars a night.

Jolie, 31, arrived in Costa Rica last week as part of her work as a goodwill ambassador for the United Nations High Commissioner for Refugees. She and Pitt spent Christmas Day with Colombian refugees.

She co-stars in the Universal Pictures drama "The Good Shepherd" with Matt Damon and Robert De Niro. Pitt stars in "Babel," a Paramount Vantage release.
