Angelina Jolie stopped by the set of Brad Pitt's movie World War Z today in Valletta, the capital city of Malta. The Jolie-Pitt family has been hanging out on the Mediterranean island for the last week while Brad works on the film, and Angelina even took the kids for an afternoon out at a playground to kick off their stay. She took off for a few days, though, to visit refugees along the nearby border of Syria and Turkey — one sign greeted Angelina as "goodness angel of the world" as she touched down at a Turkish camp. Angelina then went on to give a talk in Lampedusa, Italy, as a UN Goodwill Ambassador. Her visit to the war-torn region came just a few days after she launched her latest PSA for World Refugee Day. Following her philanthropic duties, Angelina and Brad had a romantic dinner date last night to celebrate her return to the island. The pair were spotted sharing an al fresco meal and catching up over wine and seafood.
