The young British royals took a tour of Warner Bros. Harry Potter studios in London earlier today.
The royal siblings and William's pregnant wife Catherine had a look around the set of the popular wizard franchise today.
The trio were visiting to officially inaugurate the Warner Bros. studio in London, which was home to all the Harry Potter films and many other blockbusters.
They clearly had a great time testing out props from popular films, such as Batman's suit and his infamous Batmobile.
"To be honest, I’m over the moon just to have seen the real Batmobile and Batpod – you don’t do baby seats for those cars, do you, by any chance?" William laughed.
"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."
William is a big fan of author J.K. Rowling's popular Harry Potter character, praising her for her entertaining novels.
“The journey to today began most obviously with the now-legendary story of an aspiring author, J.K. Rowling, translating her phenomenal imagination on to paper in the form of the Harry Potter series. But in another sense, the journey to today began way before, as this country has a long and proud literary and visual arts history - a history unmatched in the world for its variety, commercial success and longevity," William said during a speech.
Coinciding with London's Sundance film and music festival, the royals want to promote British movies and art.
William drew on several examples to prove how important creativity is.
“Our capacity to produce brilliant works continued into the 20th century with the great British pioneers of film and TV, both here and in Hollywood," he continued.
“The London Olympics opening ceremony reminded us as a nation just how diverse, talented and entertaining the British creative industries have always been.”
Following William's speech, they were shown around the studios and even given a magic lesson complete with wands.
Also attending were around 500 children and their parents, all associated with charities the royals are patrons of.
Before leaving, Catherine, William and Harry held a meeting in the Great Hall, which was used in the Harry Potter films, to discuss their charity involvement.
Chief executives for over 35 of the voluntary organisations attended the event.
Catherine looked stunning as she showed off her baby bump in a polka dot dress from UK high street store Topshop, while the two princes looked dapper in suits.
