WATFORD, England (AP) — Britain’s young royals are having a magical day out with a visit to the studio where the "Harry Potter" movies were filmed.

Prince William, the Duchess of Cambridge and Prince Harry are touring Warner Bros. Studios Leavesden near London, home to the Making of Harry Potter studio tour.

The royals, accompanied by 500 children and adults from charities they support, are getting a wand lesson, visiting Hogwarts’ Great Hall and seeing props, costumes and models from the Potter series.

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

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