Friends will watch The Crown before Prince Harry to warn him of any scenes that might re-traumatise him, source says (and William just won't watch)

Prince Harry will have a 'sensitivity viewer' watch The Crown's depiction of his last call with his mother Princess Diana to 'save him' from traumatic content, an insider has claimed.  

The first four episodes of the final season will show a dramatised version of the lead-up to and the aftermath of Diana's death, including the Princess of Wales's last meeting with her sons.

But a newly released clip from the Netflix series shows them missing a phone call at Balmoral from Diana, played by Elizabeth Debicki, on the day before she died.

The new season will also show the imagined last conversation the Princes had with their mother as well as the moment they were told of their mother's death.

Despite knowing the four episodes will focus mostly on Diana's death, Harry is still likely to watch the series. He previously said he watches and reportedly even fact-checks the show.

An insider has now told the Telegraph they 'may watch it first in order to save him from anything he may not wish to see'. 

But Prince William is unlikely to watch the series, after he previously expressed frustration over the show glossing over the circumstances surrounding Diana's Panorama interview. 

Newly released clips from The Crown include Charles' despair over telling William and Harry their mother has died and Diana telling Dodi she's a 'persona non-grata' at Balmoral.

The show will also depict the last time Prince William and Prince Harry spoke to their mother - but it will not be a true reflection of the conversation.

In episode four, Diana is depicted as frustrated while in Paris with Dodi, and desperate to return to the UK to see her sons. 

After missing one opportunity to speak with them on the phone, Diana finally manages to have a call with Prince William and Prince Harry, where they ask her if she's going to marry the son of billionaire Mohamed Al-Fayed.

Although it is true that Prince William and Prince Harry shared a phone call with their mother on the last day she was alive, their recollections of the call do not reflect the Netflix series' depiction.

Speaking in a 2017 documentary Diana: Our Mother, the Princes discussed for the first time the details of their 'desperately rushed' final call with the late royal.

Recalling the chat, they expressed their regret that they were desperate to go back outside and play with their cousins, who were also at Balmoral.

Harry said: 'I can't really, necessarily, remember what I said. But all I do remember is probably, you know, regretting for the rest of my life how short the phone call was.

'And if I'd known that was the last time I was going to speak to my mother – the things I would have said to her.'

William said of the call: 'Harry and I were in a desperate rush to say goodbye, you know, "see you later".'

Neither of the two has revealed Diana's precious final words to them. 

The emotional first four episodes cover the tragic car crash in Paris that killed Princess Diana in August 1997 – alongside her lover Dodi and their chauffeur Henri Paul – and the Royal Family's reaction to it, as well as the summer holiday Diana and Dodi enjoyed in St Tropez prior to the tragedy. 

For sensitivity reasons the exact moment of Diana's death is not re-created, but there are controversial scenes in which Charles tenderly converses with an imaginary Diana in the cabin of the royal plane as he accompanies her body from Paris to London, and later when she also appears to the Queen.

Critics who have seen these scenes called them 'farcical' for portraying Diana as a ghost, but series creator Peter Morgan has insisted that wasn't the intention.

'I never imagined it as Diana's ghost in the traditional sense,' he told Variety magazine. 'It was her continuing to live vividly in the minds of those she has left behind.'

The final six episodes of the series, which will be available in December, will see the family moving on from Diana's death and cover William and Kate's budding romance at St Andrews, finishing with Charles and Camilla's wedding in April 2005. 

Netflix boss Ted Sarandos has explained why the series ends there. 'It was the cut-off to keep it historical, not journalistic,' he said. 'By stopping almost 20 years before the present day, it's dignified.'
