William and Harry Haunted by Final Phone Call With Princess Diana

Princes William and Harry are opening up about their biggest regret, their last phone call with their mother. William was 15 and Harry was just 12. The princes were vacationing in Scotland and their mother was in France with her boyfriend, Dodi Fayed. The moment is recounted in a new documentary directed by Ashley Geffing. She calls in and Prince William's playing. He goes to the phone, chats to her, wants to get out and play with his cousins. Hands over to Harry who does the same thing. Both of them just are desperate to go out and play. Prince Harry sort of says that that conversation will kind of haunt him for the rest of his life. In the HBO documentary film, Diana, Our Mother, Her Life and Legacy, the princes remember their mom as a prankster. She was one of the naughtiest parents. She would come and watch us play football and smuggle sweets into our socks. I mean, literally walking back from a football match and having sort of five packets of Starburst. William, a father of two, says he makes sure his kids know his mother as Granny Diana. I do regularly put in George a chart to bed to talk about her and just try and remind her that there are two grandmothers, there were two grandmothers in their lives. In this scene, Elton John shares his memories of Diana with Prince Harry. She had this incredible ability, which he kind of inherited and I told him that and he said, thanks very much, to make people feel at ease and make them feel that everything's gonna be all right. Princes William and Harry are also sharing never-before-seen personal photographs from their family album. Prince Harry is with his mother on the royal yacht and here, William and Harry are dressed as police officers. They told us before the interviews that they'd never spoken about her at length before and would never speak about her at length again.
