The documentary is expected to air in July.

ITV plan on sharing some very rare footage of Princess Diana in a brand new documentary marking her 60th birthday. The film, which is called Diana, will air this July. As well as some rare clips, the documentary will provide viewers with a deeper insight into Diana's private life through photos and letters. Diana passed away in a car crash in the Pont de l'Alma tunnel in Paris in 1997. She would have turned 60 this year. Ahead of the film's release, ITV's Jo Clinton-Davis said: "This year would have been Diana's 60th birthday, and the intention with this landmark documentary is to offer the definitive account of her life, both in front of the cameras and behind the scenes. "It is a difficult undertaking to shed new light on the most emotional, dramatic and pivotal elements of Diana's life, when that light still burns brightly." She continued: "But by delving deep into her relationships with friends, colleagues and staff, our aim is to provide a vivid portrayal of the woman who became known as the Queen of Hearts." 72 Films will work alongside ITV to produce the film. The company's producer, David Glover, spoke about how Diana's story still captivates audiences all these years later. He said: "There is something a bit magical about Princess Diana, and despite the difficulties in her personal life she managed to use her connection with people to do huge amounts of good. "Her 60th birthday feels like the perfect time to re-examine her life and legacy and explore just how she went from a relatively unknown teenager to the most mourned person who ever lived." A specific release date for the documentary has not been announced, although, given its premise, it's likely to air some time around Diana's birthday in July.
