British royals PRINCES WILLIAM and HARRY face fresh anguish after hearing a movie is planned which claims their late mother Princess Diana was murdered. Diana, Princess Of Wales died in 1997 after a high speed car accident in Paris. But the new movie will depict a journalist, played by House star Jennifer Morrison, probing conspiracy theories about her death. The news follows the furore over U.K. TV network Channel 4's decision to broadcast graphic images of Diana's final hours in a documentary that was aired on Wednesday (06Jun07) - despite appeals from William and Harry to scrap the footage.
