A HARROWING new film about Princess Diana premiered last night and caused instant outrage among royal experts who said it strips her of dignity.
The movie, Spencer, portrays Diana as an emotionally unstable, broken woman who self-harms and breaks down hysterically in front of young son Prince William.
Graphic scenes range from the fragile princess fantasising about throwing herself down the stairs to choking on a pearl necklace gifted to her by husband Charles.
She is shown at the height of a mental health crisis while battling bulimia — reduced to tears as she forces herself to vomit and descends into hallucinations about her own death.
A degrading shower scene ends with the princess talking about a solo sex act.
Ingrid Seward, editor in chief of Majesty Magazine, said: “It is really cruel to portray her like this. It is totally unnecessary.
“William and Harry will be very angry and hurt about this. They will find it horrible that their mother is being portrayed in such a huge movie this way.”
Royal biographer and expert Penny Junor agreed, and said: “It is unnecessarily gratuitous.
“Poor William is all I can say.
“And let’s leave Diana with a shred of respect and dignity.
“I know William was there when she was unhappy but it sounds to me the movie is factually incorrect.”
One intense imagined scene, sees William close to tears and begging his mother to join him for dinner after she locks herself in the bathroom following graphic self-harm attempts.
After Diana — played by ex-Twilight star Kristen Stewart — appears with mascara-stained cheeks, she asks her son if he saw Camilla Parker Bowles at the church on Christmas morning.
Prince William slammed the BBC for “exploiting” his mother following the 1995 Martin Bashir Panorama interview scandal.
Let’s leave Diana with a shred of respect and dignity.
He said: “It effectively established a false narrative which, for over a quarter of a century, has been commercialised by the BBC and others.”
Actress Kristen, 31, was wearing a strapless silver gown at last night’s premiere in London.
Spencer has been tipped as an Oscar candidate — largely due to her portrayal of the princess.
SPENCER is very much a tale of two halves.
On one hand, it deserves a standing ovation for Kirsten Stewart’s portrayal of the princess, with her near perfect execution of her accent and mannerisms.
But the other is the questionable warping of history.
The film seems intent on erasing any possible positive influence or support any member of the Royal Family offered Diana — and presenting it as fact.
Spencer is at times an uncomfortably insensitive watch riddled with holes that throws unnecessary new mud at a British icon.
