"Brad was in one car with some of the kids and Angelina was in another with the others. They were all smiling and looked really happy, but then I suppose it's not every day that a kid gets to have their own train to play with!"

The sleek, silver-and-red Virgin train that had been specifically chartered for the Jolie-Pitts and estimated 350 associates and crew pulled into Glasgow Central Station at 2:30 p.m. And there were about 100 fans gathered to try to catch a glimpse of the famous family.

For the next few weeks, the World War Z team will take over the main square of Glasgow (just a few blocks from the train station), which has been converted to look like the American city of Philadelphia to a convincing degree.
