12 things you probably didn't know about 'The Devil Wears Prada'

In a 2016 interview with Variety, Hathaway said she "wasn't the first choice" for the role of Andy Sachs, a recent journalism grad who landed the coveted role of personal assistant to a major magazine's editor-in-chief.

Movie director David Frankel was choosing between around 100 actresses, including Rachel McAdams — who turned down the role multiple times. He eventually chose Hathaway.

Despite reading the script and feeling like the movie was going to be a huge success, Streep had reservations about accepting the role of Miranda Priestly.

Streep said she was hesitant because when she was offered the role, producers low-balled her salary.

The actress told Variety that when she decided to walk away from the role, producers doubled their initial offer.

The book "The Devil Wears Prada" isn't classified as non-fiction, but the New York Times Best Seller is written by Lauren Weisberger, who was once an assistant to the editor-in-chief of American Vogue, Anna Wintour.

Although the novel isn't entirely based on real-life, Weisberger has said her former job influenced how she wrote the story.

"It wasn't a one-to-one portrayal [of Wintour]," Weisberger told the Daily Mail in 2010. "But of course my time at Vogue informed the book, there's no denying that."

"We bought it as a partial manuscript, 50 pages with an outline, as Lauren Weisberger was writing the book," Former Fox 2000 chief Elizabeth Gabler told IndieWire.

"The idea was so strong, the concept so clear and so enticing, that we thought we would be able to figure out a movie from it no matter what the eventual manuscript turned out to be," she explained.

Emily Blunt famously played Emily Charlton, Miranda's snide first assistant, in the film.

And, in 2008, the British-American actress told the New York Times that the character was actually supposed to have an American accent.

"Originally, the character was supposed to be American, but I felt she should be British," Blunt told the publication. "British people in America always sound so desperate and clipped. In the fashion world, there was a slightly snobby reaction to my character. They felt the hair, the makeup, and the clothes were wrong. "

In the cut-throat world of magazine fashion, you've got to dress to impress, but that can come at a cost — even on the big screen.

The costumes for "The Devil Wears Prada," which were designed by Patricia Field, cost over $1 million.

Field told Glamour magazine that she was really excited when Streep decided to dye her hair white for the role of Miranda Priestly.

"I was so elated because, for me, white hair was something I could play against any color. The white gave me a backdrop and a bigger freedom ... it gave me the opportunity to be more creative, because it started the palette, painting the portrait for me," she told the publication.

"The director and producers asked me to gain 10 pounds," Hathaway told People magazine in 2006.

But after costume fittings, Hathaway said the film's costume designer, Field, told her to lose 10 pounds in order to fit in some of the couture pieces.

"It was a nightmare. It took me about a month to gain it and two months to lose it," Hathaway, told the publication, adding that at some points in the film she wore special padding to make it look like she hadn't lost weight.

As IndieWire reported, the film was shot across New York and Paris, France, in 57 days.

In the final scene of the movie where Miranda and Andy are sitting in a car with a private driver, the very last thing Miranda says is, "Everybody wants to be us."

The script originally said, "Everybody wants to be me," but the line was altered by Streep during a table read.

Had it not been for Blunt and Stanley Tucci's roles in "The Devil Wears Prada," Tucci, who played Nigel in the film, may not have met his now-wife.

Blunt told Variety that Tucci and her sister, Felicity, met at her 2010 wedding to actor John Krasinski.

Tucci and Felicity, who is a literary agent, later wed in 2012.

In 2018, Weisberger released "When Life Gives You Lululemons" the follow-up novel to her debut book "The Devil Wears Prada."

The book follows fan-favorite Emily through her new life in the suburbs of Connecticut.
