Wills and Kate played a starring role at Leavesden’s Warner Bros. Studios on Friday as they took a magical behind-the-scenes tour of the creative hothouse where the Harry Potter books were translated to the big screen.
The parents-to-be were joined by Prince Harry as they strolled through Diagon Alley, practiced their wand skills and were welcomed to the Great Hall of Hogwarts School of Witchcraft and Wizardry.
The royal trio were visiting to take part in the studios’ official inauguration. They also brought along 500 adults and children from the charities of which they are patrons.
Kate showed her bump in a polka dot cream dress and smart black blazer, going dot to dot with Potter author JK Rowling, who also wore a polka dot number in the fashionable nude shade while on the tour.
The royals met the millionaire author during an exclusive showing of props and costumes from the Dark Knight trilogy of Batman films before entering the Making of Harry Potter attraction.
Prince William, who had said he was excited to see the Batman memorabilia, got the chance to climb into the khaki-coloured ‘Tumbler’ Batmobile from the latest film, The Dark Knight Rises.
He then gave a speech to officially inaugurate the studios, saying: “I’m over the moon just to have seen the real Batmobile and Batpod – they don’t do baby seats for those cars, do they?
“On the other hand Harry’s just excited to see a real life talking owl in the Harry Potter studios. I haven’t told him yet that Harry Potter is fictional, so please keep the secret for a little longer.
“Catherine, Harry and I are very much looking forward to the Harry Potter Studio Tour coming up shortly, and thank you to Warner Brothers for hosting hundreds of children from the charities of which we are fortunate enough to be patrons.”
Also present to welcome the Duke and Duchess of Cambridge and Prince Harry were Matthew Lewis and Bonnie Wright, who starred as Neville Longbottom and Ginny Weasley in the Potter film series.
Matthew, 23, said: “Today has been great. I was told we would be coming and that we would be meeting William, Kate and Harry, which was fantastic.
“It’s just weird being back at the place where I used to work for 10 years, and then to have the actual royal family here too is amazing. I have been on the tour before but haven’t been back in the actual studios since I finished filming.
“It’s so weird and really surreal being back after all this time. Harry joked that we must just take people round here now.”
After the magical tour, which included a stop off in Dumbledore’s office and the Weasley kitchen, William, Kate and Harry then chaired a meeting of their Charities Forum.
Vice president of the Warner Bros Studio Tour Sarah Roots said: “It has been thrilling, it was an amazing day for us and a true honour to welcome the Duke and Duchess and Prince Harry. We have been able to show them all of our authentic and original sets for the film series which were all built here.
“They loved the Great Hall, it is our biggest set. I think they have had a fabulous time and it is great that the charities have been able to get really close to William, Kate and Harry which is really inspiring for them.”
