The Duke and Duchess of Cambridge, along with Prince Harry, visited Leavesden, Hertfordshire on April 26, 2013, where the trio officially opened the Warner Bros. studios where the Harry Potter movies were made. Catherine, who is six months pregnant, wore a black and white polka-dot dress and black jacket for the event. The royal trio were shown costumes, models, and props that were used in the filming of the Harry Potter movies. They also saw vehicles used in the Dark Knight Batman trilogy, including the Batpod and the Tumbler. Prince William took a go at trying out the Batpod while his wife and brother watched in amusement. William gave his verdict on the Batpod, saying “It’s awesome, absolutely incredible.” Harry then put his fingers beside his head and said to William, “You need the ears.” Some 500 children and their parents who have an association with charities that are patronized by William, Catherine, and Harry, were also present.
