Brad Pitt touched down in London by helicopter this afternoon after traveling back from the set of World War Z in Glasgow. The flight has become part of Brad's routine commute since moving his family to the UK for production last month. His time overseas hasn't been all about work, though, since Brad and Angelina Jolie have taken advantage of their location with fun outings. The Jolie-Pitts saw The Smurfs over the weekend, but Brad took a few of the children to a movie on his own during the week. Angelina has also been out with the kids solo, recently taking Zahara and Shiloh on a girls' only shopping trip.
