As such, Kate Middleton recently reserved a delightful surprise for her children: a visit to the set of the upcoming Harry Potter prequel series. The exclusive behind-the-scenes look at the new wizarding world took place on Friday, September 26, according to the Daily Mail. During their visit, the film set took over Windsor Great Park, not far from the royals’ new home at Forest Lodge. The Harry Potter saga, adapted from the novels by J.K. Rowling, has long been a favorite of the royal family. In 2024, the sovereign revealed that she read the Harry Potter books to George, Charlotte, and Louis, admitting, however, that the king was much better at the exercise.
