Video: Duchess Kate and William have wand fight at Harry Potter tour

They've been married for two years on 29 April but, it seems, the magic is well and truly still alive between the Duke and Duchess of Cambridge.

The pair attended the official opening of the Warner Bros studio in Leavesden, Hertfordshire, on Friday - and engaged in a wand fight at the Magical World of Harry Potter tourist attraction next door.

After Prince William had a sit on the Batpod from the Dark Knight film, he joined his wife and Prince Harry in the Harry Potter tour, where he had the duel with Kate.

According to the Daily Telegraph, he said: "Where's my brother, why isn't he doing this?"

They then took part in a wand lesson with instructor Scott Heron, before the Duke, using a replica of Harry's wand, tried to disarm the Duchess with an "Expelliarmus" spell, declaring "I win!".

According to Heatworld.com, in a speech, Prince William said: "To be honest, I'm over the moon just to have seen the real Batmobile and Batpod – Josh, Barry, you don't do baby seats for those cars?"

"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."

The royals also enjoyed seeing the Harry Potter sets, including the Great Hall, Dumbledore's office and Hagrid's hut, as well as being introduced to JK Rowling herself, as well as actors Bonnie Wright (Ginny Weasley) and Matthew Lewis (Neville Longbottom).

Making a cheeky joke at Harry's expense, referring to his ginger hair, Bonnie said: "He should join our family."

The £100 million Warner Bros studios have been the location of many UK films, including the Dark Knight Batman trilogy, as well as The Phantom Menace, and Goldeneye.
