Prince William slips his favourite 'unroyal' pastime - and it may surprise you

Prince William said his “unroyal” way to switch off involves music and films, adding that he loves immersing himself in deep-thinking movies. He singled out director Christopher Nolan as a firm favorite, praising the psychologically dark and layered style of the Dark Knight series while saying he also likes action but prefers something different. The future king also revealed that the Wales household is currently hooked on the BBC reality show The Celebrity Traitors, with Princess Charlotte and Prince Louis reportedly “obsessed.” William said he even played a prank on former EastEnders star Ross Kemp after seeing him the day after the show’s first episode. He attended the Earthshot Prize event next month in Mumbai, and the Earthshot Prize edition of The Graham Norton Show will air on BBC One on Saturday at 10:40pm.
