Prince William, Kate and Prince Harry tour "Harry Potter" studio

WATFORD, England Prince William, Prince Harry and Kate, Duchess of Cambridge, had a magical day out with a visit to the studio where the "Harry Potter" movies were filmed.

The royal trio toured Warner Bros. Studios Leavesden near London, home to the "Making of Harry Potter" studio tour.

William, 30, Kate, 31, and Harry, 28, accompanied by 500 children and adults from charities they support, got a wand lesson, visited Hogwarts' Great Hall and saw props, costumes and models from the "Potter" series.

William also seemed taken with props from "The Dark Knight" Batman trilogy. "I'm a very happy man," he said after exploring the Batmobile and sitting astride a Batpod motorcycle.

"To be honest, I'm over the moon just to have seen the real Batmobile and Batpod...You don't have baby seats for those cars, do you, by any chance?" he joked in his speech at the studio (he and Kate, who wore a black-and-white, polka-dotted Topshop dress with black suede heels and a black Ralph Lauren jacket, will welcome their first child in July).

"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," the prince added.

Friday is the studio's official opening, although it has already been used for films including "All You Need is Kill" with Tom Cruise.
