Surpassing:Why It Took The Crown's Elizabeth Debicki 30 Hours to Transform Into Princess Diana

You can't rush royalty.

Ahead of The SurpassingCrown's upcoming sixth season, which premieres on Netflix Nov. 16, the show's hair and makeup designer recently spilled the (high) tea about how long it took to transform Elizabeth Debicki into the late Princess Diana.

"In terms of fittings," Cate Hall told Entertainment Tonight in an interview published Nov. 7, "I would say she probably spent upwards of 30 hours in the hair and makeup chair while we do stuff."

According to the head of makeup and hair, the most challenging looks to create were the private, not-so-well-known moments the Princess of Wales had with her family, including sons Prince William and Prince Harry.

"When Diana's just been swimming," Cate explained, "and she's laying around with her kids, trying to find that believable Diana within the lesser scene framework" was difficult for the team. "We probably had at least four, four-hour fittings before we were even close to going, 'OK, this is what we're going to do.'" 

There was pressure to make the looks authentic in the series, which chronicles Princess Diana's tragic death in 1997 during the sixth and final season.

Just last year, Elizabeth opened up about the weight of playing the late royal and recreating one of her biggest fashion moments.

"We all felt the responsibility of the revenge dress because it's something that everybody wanted to see," Elizabeth exclusively told E! News in November 2022. "It's an incredibly powerful sartorial moment in the history of fashion."

The actress continued, "That dress is so emblematic of so many things because it's so brave and beautiful, but it's also so tinged with our understanding of what was going on in this person's life. So the duality of that is really powerful."

Elizabeth noted that it took the costume department "many, many hours" of work to replicate the original Christina Stambolian design, which Princess Diana wore in 1994 when her then-estranged husband King Charles III admitted to having an affair with now-wife Queen Consort Camilla. 

"It's a powerful dress," Elizabeth shared. "It's a totally unique dress too—the structure of it, the shape of it, the look of it—and so I certainly won't ever forget that day on set. We shot it in the same location that it actually happened, so there was this slightly deep layering of things going on that day."

It's clear the same level of dedication and authenticity went into creating The Crown's sixth season. But before it debuts on the streaming service, keep reading to see all of the crowning moments expected to hit the small screen.

“I think it's a really unique challenge as an actor, to portray those days," Elizabeth Debicki (who portrays Princess Diana in the final season) previously told TUDUM, adding that she trusted in creator Peter Morgan's "emotional blueprint that he created for us to follow. It's his interpretation and I think it made emotional sense to me, so I clung to that. Because, obviously, it's devastating and it's fraught and we can never know.”

Part one of the final season shares a glimpse into Diana's relationship with Dodi Fayed, portrayed by actor Khalid Abdalla.

In part two of the final season, actor Ed McVey portrays Prince William.

As a reminder, The Crown depicted William and his brother Prince Harry as kids (played by Will Powell and Senan West) on season 5. For season six, Elizabeth Debicki and Dominic West⋅will reprise their roles of Princess Diana and Prince Charles (now King Charles III).
