Brad Pitt waved to a pair of pint-sized fans on the set of World War Z in Malta today. He was once again decked out in his now-familiar shirt and scarf, which we also saw his body double wearing while shooting a particularly gruesome zombie scene earlier in the week. The film may be dark, but the set is still a family-friendly spot and Brad brought Pax for a visit one day while Angelina stopped by with Shiloh and Zahara on another sunny afternoon. While Brad is hard at work on his new project, we also got a glimpse of Angelina's latest venture as well. Louis Vuitton released a teaser video of Angelina Jolie in Cambodia, giving us a peek at her full ad campaign, which will be out soon.
