In a publicity spell more powerful than even the most astute teenage wizard could dream up, Harry, William and Kate today attended the opening of the new British Warner Bros. Studios tour. The studio tour encompasses many of the sets on which the Harry Potter series was filmed.
Including the unborn, the second, third and fourth in line to the throne were all present.
The highlights of their visit today will include a tour of the Harry Potter sets, including a wand lesson in The Gryffindor Common Room.
Oh, and Kate's polka dot dress? $50 from Topshop, people.
William had a blast when he got up on the Bat Bike while experiencing the new tour.
Kate looked on giggling dutifully.
William, a keen Ducati rider, turned to Harry and whispered: 'We should borrow that for the weekend.'
