Prince William And Kate Duel With Magic Wands And Ride The 'Batpod'

Prince William, Prince Harry, Kate Middleton and her polka dot-clad baby bump toured the new "Harry Potter" and "Batman" exhibits at the Friday launch of Warner Bros. Studios in Leavesden, England.

During a speech to inaugurate the studio, Prince William joked he would like to “borrow” the Batmobile for the weekend and teased his younger brother Prince Harry, saying "I haven't told him yet that Harry Potter isn't real."

"I'm over the moon just to have seen the real batmobile and batbike,” he added. “You don't do baby seats for those cars do you?"

Turns out Prince William is a pretty big "Batman" fan, publicly pleading "Please make another in the 'Dark Knight' series. And another, and another."

William even joked about taking over the "Batman" role, saying "Christian Bale's getting old and tired. I will stand in if I have to."
