Brad Pitt has been a very busy bunny lately – he, Angelina Jolie and their 6 children are in the UK while Brad films his latest flick, World War Z. In addition to that, Brad took on the parental duties over the weekend and took the kids to the movies and gave Angelina a break. It’s a fair swap since Angelina has really been entertaining the kids all over London.

Brad certainly had the fashion right for the event – that grandpa sweater was definitely the right costume for the day. And no doubt Brad was thinking he would do whatever would help the situation – it’s not easy to wrangle 6 kids under the age of 10!
