A new documentary celebrating Princess Diana's life and work is on its way 20 years after her tragic death.

Deadline reports that the doc will focus around interviews with the late princess' sons Prince William (a.k.a. the Duke of Cambridge) and Prince Harry and both "talk openly and in depth about their mother and how her influence has shaped their lives." There will be a focus on her charity and humanitarian work, particularly with land mines, child bereavement, homelessness, and HIV and AIDS. HBO and British television network ITV will premiere the film later this year.

"This new ITV film will offer viewers a fresh and revealing insight into Princess Diana through the personal and intimate reflections of her two sons and of her friends and family, many of whom have never spoken before, to bring together a definitive portrait of a unique person who touched the lives of millions," said ITV exec Jo Clinton-Davis.
