Emily Blunt surfaced on the set of The Devil Wears Prada 2 this week with a hairdo totally unrecognizable to fans of the original 2002 film. 

Meryl Streep starred in the first movie as the fearsome fashion editor Miranda Priestly, who was inspired by the now outgoing Vogue chief Anna Wintour.

The original novel was a roman à clef by the real Anna’s former assistant Lauren Weisberger, whose fictional stand-in Andrea ‘Andy’ Sachs was portrayed in the silver screen adaptation by Anne Hathaway, 42.

Meanwhile Emily played Miranda’s chic, perpetually harried senior assistant Emily Charlton, who hisses that she is ‘one stomach flu away from my goal weight.’

Viewers of the original movie will remember Emily’s trademark copper red locks, which elegantly framed her perpetually severe expression.

For the sequel, however, Emily is swapping out her previous hair color for a head-turning ash blonde do that she debuted on set in New York this Thursday.

She was previously spotted on the set of the new movie with the same hair color and same style she had sported in the 2006 original.

Evidently, however, her character will undergo a makeover during the course of the sequel, resulting in the new look she unveiled this week.

The scene she was filming involved a restaurant meeting with Anne, who could be glimpsed sitting with her at an elegant table near the window.

Emily’s fashion-forward outfit included a trendily torn, scarlet and black striped top with ‘NY’ splashed across the front, perfectly fitted to her enviably lithe frame.

She pulled a high-waisted black skirt over a set of matching shorts, which were cut revealingly enough to show off her vertiginous legs.

The Oppenheimer actress accessorized with a chain mail tie, bringing the look together with towering platform heels and sunglasses.

Emily sharpened her unmistakable screen siren features with makeup, including a slick of blood-red lipstick that complemented her top.

When she was spotted emerging from her trailer at another point during the workday, the skirt-shorts combo was swapped out for crimson slacks.

A stylish jacket that matched the slacks was slung over one of Emily’s shoulders, and she augmented the outfit with a handbag and a camel-toned baseball cap.

During the sweltering New York August day, a member of the crew could be seen walking alongside Emily holding an umbrella over her to ward off the rays.

When the first film came out, Emily’s character was rumored to be inspired by former Vogue writer Victoria ‘Plum’ Sykes, who herself has strenuously denied as much.

A number of boldface names from the first movie have returned for the sequel, including not only Meryl, Anne and Emily but also Stanley Tucci.

Stanley was a scene-stealing presence in the first film as Runway magazine’s waspish art director Nigel Kipling, who announces Miranda’s arrival at the office by warning his colleagues: ‘All right, everyone, gird your loins!’

David Frankel and Aline Brosh McKenna, the director and writer respectively of the original movie, have been enlisted for the same jobs on the sequel.

New faces have also joined the team, from Kenneth Branagh as Miranda’s new husband to Australian heartthrob Patrick Brammall as Andy’s latest love interest.

Timothée Chalamet’s sister Pauline and The Office actor BJ Novak were also seen last month working on the movie in New York.

Although Lauren Weisberger wrote a sequel to her novel called Revenge Wears Prada, the reported plot of the second film is different from that of the second book.

In the upcoming movie, Miranda is said to be attempting to steer Runway through a new media landscape as her old world of print magazines slides into increasing irrelevance in the digital age, according to Variety.

She is bent on making a deal with a luxury ad firm, only to hit a snag in the shape of Emily, who is now an executive at the company.

When the book The Devil Wears Prada was published in 2003, it spent six months on the New York Times bestseller list and set off a blizzard of gossip that Lauren was writing about her former boss, who had employed her for less than a year.

In public, the real Anna Wintour kept her cool, breezily remarking that she was ‘looking forward to reading the book’ to the New York Times.

However one of Anna’s subordinates claimed to her unauthorized biographer Jerry Oppenheimer that the Vogue capo was ‘spitting fire’ behind the scenes and ‘felt she had been used and abused by Weisberger.’

When the movie came out three years later, Anna leaned into the publicity and attended the New York City premiere wearing Prada.

Several years after the film’s release, Anna was asked in a CNN interview whether she regarded her ex-assistant’s novel as a ‘breach of trust.’

‘Well…,’ Anna replied with a weak laugh. ‘I think that she brought attention to fashion in a way that, you know, you can look at it in a negative way or a positive way. I choose to look at it in a positive way. In some ways, I think I should be grateful to her.’
