Diana, Our Mother features interviews with HRH The Duke of Cambridge and HRH Prince Harry, both of whom talk openly about their mother and pay tribute to the many ways her influence has shaped their lives. The film offers a fresh and revealing insight into Princess Diana through the personal and intimate reflections of her two sons and her friends and family, many of whom have never spoken publicly before, to bring together a unique portrait of an iconic person who touched the lives of millions.

The 65-minute film includes never-before-seen photographs of Diana, taken from an album that she had assembled. The brothers look through the private family album and recall some of the most joyful and touching moments from their childhood.

Studying a photo of The Princess holding him while pregnant with Prince Harry, Prince William says: "Believe it or not, you and I are both in this photograph, you?re in the tummy.?

Prince Harry says: ?This is the first time that the two of us have ever spoken about her as a mother.?

Prince William says: ?She was very informal and really enjoyed the laughter and the fun.?

Prince William and Prince Harry share some of their earliest memories of their mother, recall the final conversation they had with her before her tragic death in August 1997, and discuss their feelings in the aftermath of losing her. Prince William explains how he keeps her memory alive for his own children.
