Love her or loathe her it is hard to deny that the Duchess of Cambridge has cast a spell over the general public - or the tabloids, at least. Today accompanied by her husband the Duke of Cambridge and brother-in-law Prince Harry the spellbinding affect was compounded by the fact trio were in Leavesden, Herts to officially open the Harry Potter Warner Bros studios to the public.
The three royal wizard fans arrived together by car at the studios where the popular film adaptations of JK Rowling's bestselling novels were made. Kate, who is around six months pregnant, wore a black jacket and a £38 polka dot dress from Topshop and she, William and Harry were introduced to local dignitaries and senior executives from the film studio.
The large sprawling site close to Watford is home to the popular Making Of Harry Potter tour that has proved a huge attraction for fans of the teenage wizard. Props, costumes and models from the movies that chronicle his adventures were on display for the royal guests.
Also invited for the visit were 500 children, and their parents, associated with charities that have one of the royals as their patron. Futuristic vehicles from the Dark Knight Batman trilogy, made by Warner Bros and starring Christian Bale in the lead role, were the first items on display including the Tumbler - the caped crusaders' Batmobile and his bike the Batpod.
William joked about taking over the Batman role with Josh Berger, president and managing director of Warner Brothers UK, Ireland and Spain, telling him: "Christian Bale's getting old and tired... I will stand in if I have to."
