Spencer: Kristen Stewart seen with actors playing Princes William and Harry for Princess Diana film

Kristen Stewart was seen with the young actors playing Princes William and Harry for the first time as she shot more scenes for upcoming biopic Spencer on Monday. 

The actress, 30, transformed into the late Princess Diana while filming at a drive-in KFC on the Old Kent Road in London and was seen stepping out of a Porsche alongside the two young stars.

Looking every inch the part, Kristen donned a navy blazer over light jeans as well as a baseball cap as she helped the two smiling boys out of the sports car.

Kristen’s ensemble was reminiscent of Diana’s outfit worn to the Guards Polo Club in 1988, where the royal rocked a casual sweatshirt with the British Lung Foundation logo on the front as well as jeans and a blazer.

While filming in London, Diana swapped her boots from that former occasion for white trainers and seemed to be wearing a plain cream jumper rather than a printed top.

She wore her blonde locks down and perfectly styled under the cap before completing her costume with a pair of large black sunglasses.

The two younger actors also looked the spitting images of Prince William and Prince Harry, with the younger of the duo sporting Harry’s golden locks and a brightly coloured padded jacket as he climbed out of the car.

During the sunny shoot on Monday – and also on another day of filming on on Norfolk’s picturesque Hunstanton beach last week – a green Porsche was used for Diana’s car.

However the royal was more often seen giving her two sons lifts in an Audi A4 convertible, which boasted a similar dark green colour and soft-top roof.

Kristen has been seen shooting Spencer several times in recent weeks, with the actress nailing Princess Diana’s style with each ensemble.

And in a new promotional shot for the film Kristen perfectly replicates the Princess of Wales’ stunning gaze while sporting a tartan blazer that became known as one of her most iconic looks.

Filming for Spencer has been underway for several weeks, with the film set to depict the late royal in a dramatised version of a ‘critical’ weekend in the early 1990s, when Diana decided that her marriage to Prince Charles wasn’t working. 

The image shows Kristen softly smiling into the camera along with her signature head tilt, sporting a cream polo neck jumper and tartan blazer.

It was a look famously worn by Diana while she paid a visit to Portsmouth in 1989, meeting the town’s mayor and residents at Eastney Community Centre.

The image also offers a telling hint about the film’s setting, as Kristen’s Diana is still wearing her eye-catching blue engagement ring, along with oversized pearl earrings.

Spencer will follow the breakdown of her high-profile, 15-year marriage to Prince Charles [played by Jack Farthing] and is primarily being filmed at the Schloss Marquardt in Potsdam – a castle which is doubling as Sandringham Estate.

The story is said to take place over three days during one of Diana’s final Christmases at the House of Windsor in their Sandringham estate in Norfolk, England in 1991. 

The script, written by English screenwriter Steven Knight, who has also written Peaky Blinders, follows the moments Diana realised she ‘needed to veer from a path that put her in line to one day be queen’. 

Last month, an accuracy row broke out as royal experts branded the project inaccurate because it’s set on a weekend at Sandringham which never happened. 

According to royal biographers Robert Jobson and Ingrid Seward, Diana had stopped visiting the estate before the period in which the drama is set.   

Speaking on True Royalty TV‘s The Royal Beat, Robert said: ‘I don’t even think she was there that weekend. She wasn’t even at Sandringham, on this supposed weekend. 

‘The film will suggest this is where the decision was made to divorce, but she never made that decision. I didn’t think she was at Sandringham after 1990 and this was set in 1991.’

Ingrid added: ‘The film is based on three days at Sandringham, and the period that it is based on, Diana wasn’t going to Sandringham anymore.’  

Their comments follows widespread criticism of Netflix drama The Crown, which saw politicians, experts and friends of the Royal Family call for a disclaimer to warn viewers that the show twists the truth.  

Friends of close senior royals including Prince Charles even went so far as to accuse it of ‘trolling on a Hollywood budget’. 

Director Pablo Larraín explained that the drama will not delve into Diana’s tragic death, but instead focus on her relationship with the royal and the love she had for children Prince William and Prince Harry. 

The filmmaker said: ‘We decided to get into a story about identity, and around how a woman decides somehow, not to be the queen…

‘She’s a woman who, in the journey of the movie, decides and realises that she wants to be the woman she was before she met Charles.’

When the news was first announced, Twitter was swarmed with questions and comments about Kristen’s role. 

Pablo quickly defended his decision to cast the American actress in the role, telling Deadline: ‘Kristen is one of the greatest actors around today. 

‘Kristen can be many things, and she can be very mysterious and very fragile an ultimately very strong as well, which is what we need. The combination of those elements made me think of her. 

‘The way she responded to the script and how she is approaching the character, it’s very beautiful to see. I think she’s going to do something stunning and intriguing at the same time.’

Actresses that have played Princess Diana

Naomi Watts in Diana (2013)

British-Australian actress Naomi Watts famously played the Princess of Wales in the 2013 movie Diana which was derided by critics at the time. ‘Diana might have been flawed and scheming and love-starved, but this film doesn’t help explain that. Nor does it illuminate the common touch and humanitarian side that endeared her to a global audience,’ film critic Suzanne S. Brown wrote. Even Naomi herself would later admit that the film was a ‘sinking ship’.

Emma Corrin in The Crown (2020)

Newcomer Emma Corrin was cast as Princess Diana in the fourth season of The Crown in 2019, and earned critical acclaim for her portrayal of the charming but troubled young princess.

Lesley Harcourt in William & Catherine (2011)

Scottish actress Lesley Harcourt – who has had roles in British crime drama Taggart – played Diana in this cheesy Hallmark movie in 2011.  The TV drama was described as ‘superficial fun’ by critics and not taken very seriously. 

Genevieve O’Reilly in Diana: Last Days Of A Princess (2007)

This Channel 5 docu-drama starred Irish actress Genevieve O’Reilly, who is perhaps best known for her work in the Star Wars franchise as Mon Mothma. It certainly fared better than other projects, with a review in The New York Times praising it: ‘It portrays her as needy but manipulative, loving but flawed — in other words, as a human being. Blending documentary techniques and scripted drama, it gives a surprisingly credible picture of the princess’s last summer.’

Serena Scott Thomas in Diana: Her True Story (1993) 

Based on the publication of the same name by Andrew Morton, British actress and model Serena Scott Thomas also found some praise for her portrayal in this made-for-TV movie. Entertainment Weekly said Serena showed ‘great charm’ in the role, but said she ‘more closely resembles a softer version of Murphy Brown‘s Faith Ford than she does the angular princess.’ Interestingly, Serena later played Carole Middleton in the 2011 TV movie William & Kate, depicting the courtship between the Duke and Duchess of Cambridge.

Amy Seccombe in Diana: A Tribute To The People’s Princess (1998) 

This ill-advised Princess Diana tribute was released just a year after her death, and starred little known actress Amy Seccombe for the part. The project was largely ignored upon release and thought to be distasteful. Seccombe’s only other role after the TV movie was playing a medic on the TV show Operation Good Guys.

Julie Cox in Princess In Love (1996)

Based on James Hewitt’s book, this American TV movie follows the relationship that blossomed himself between Diana and James Hewitt. The role went to British actress Julie Cox who was recently seen in the crime drama Broadchurch. The title failed to have much impact upon its release. 

Caroline Bliss in Charles And Diana: A Royal Love Story (1982) 

This 1982 American made-for-television biographical drama starred Catherine Oxenberg as Diana, Christopher Baines as Prince Charles, and Hollywood royalty Olivia de Havilland as Queen Elizabeth. It originally aired September 20, 1982 on CBS. One damning review from The Washington Post called it a piece of ‘slack-jawed heraldic voyeurism incapable of, and apparently uninterested in, transforming remote news figures into believable mortals.’
