At the beginning of the movie, Elizabeth is shown reading a novel titled "First Impressions" - this was Jane Austen's original title of her novel before she altered it to "Pride and Prejudice". Additionally the text of the visible pages is readable when paused; it is the last chapter of Pride and Prejudice, with names changed.
Director Joe Wright managed to cast Judi Dench reportedly by writing her a letter saying 'I love it when you play a bitch', and petitioned Donald Sutherland to take the part of Mr Bennet. As Wright said in an interview in 2005, "We ended up having a long email correspondence about everything from 18th-century agriculture to my relationship with my father. I cast Donald a) because he's a god, and b) because you needed someone of that strength to handle those six women." On a similar note, he mentioned he was "reluctant" to cast Simon Woods as Mr Bingley, as he had previously been in a relationship with actress Rosamund Pike: "'I tried very hard not to cast Simon, but I knew he was perfect. Finally I rang Ros and asked if she'd mind, and she said, "Absolutely not". They hadn't seen each other for two years but the next day they were dancing together. It was lovely".
Joe Wright was not initially keen on Keira Knightley playing Elizabeth, believing her to be too attractive. He changed his mind upon meeting her, deciding her tomboyish attitude would be perfect for the part. Or, as she tells it on The Graham Norton Show (2007) : "He initially thought I was too pretty, but then he met me and said 'Oh, no you're fine!'."
All the exterior Pemberley sequences and some of the interior, including the sculpture gallery, were shot at Chatsworth House, property of the Duke of Devonshire. As the house functions as a private home and is also the most visited stately home in England, several of the interior shots could not, however, be done there and were instead shot in Wilton House, Wiltshire.
Joe Wright specifically instructed Keira Knightley never to pout, throughout the whole film. There is, however, one scene in where she does, but that scene was shot by the second unit without the director present. According to Knightley, Wright still complains when watching the film over her breaking this 'pout ban'.
Keira Knightley was preparing for her role in Domino (2005) while she was filming this, and had already cut her hair. She had to wear a wig during the last few weeks of filming and long sleeves to hide her muscles.
While editing the scene with Elizabeth and Mr. Darcy's first dance, Joe Wright discovered that they had inadvertently gotten the entire scene in one take via a camera in place to take establishing shots. The single take version is in the finished film.
In the book, Elizabeth visits a portrait gallery in Pemberley. This was changed to a sculpture gallery for the film in part because they were filming at Chatsworth which has a spectacular sculpture gallery, and also because Jo Wright felt it was a more dynamic way to stage the scene.
The importance of how much characters earn as interest on their inheritance is a key element to the story. Each of the Bennet girls will only inherit one thousand pounds which would mean they would only have forty or fifty pounds a year to live on. By comparison that is roughly $5000 US in 2017 figures. This makes Mrs. Bennet's desperation to marry off her daughters far more imperative.
According to the director's commentary, Carey Mulligan (Kitty) thought of her mother's funeral during her first crying scene (also her first film). On subsequent takes, when she ran dry, Carey thought of what song would be played at her own funeral. It didn't work quite as well.
The English Country Dances done in the film are: Young Widow, Wakefield Hunt, The Bishop, Dutch Dollars, Tythe Pig, Black Bess, Duke of Gloucester's March, and Moniek's Maggot (a modern composition done in the traditional style, danced in the film to a tune by Henry Purcell.)
Talulah Riley who plays Mary, the third Bennett daughter, is younger than Carey Mulligan who plays Kitty the fourth daughter. Jena Malone who plays the youngest daughter Lydia is older than both of these as well as Keira Knightley who plays Lizzie the second daughter.
The dinner table scene at Lady Catherine's was the first scene shot for the film. Elizabeth's conversation with Mr. Wickham under the tree was the last. Filming at that location, Burghley House in Linconshire, lasted from the 18th to the 22nd of July, 2004, according to the house's website. In the film (and the novel), the house is called Rosings. Filmed almost entirely on location. The only set built for the film was the Meryton Assembly room where Darcy and the Bingleys are first introduced, because assembly rooms of the type no longer survive in England, or are at least very hard to find nowadays. Building the set also allowed the crew to build it to their exact specifications. Filming on a real location that was that narrow would have been incredibly difficult anyway.
In the scene where Lizzie is asked to play the piano by Lady Catherine, she plays a very awkward version of the composition that plays at the beginning of the film and throughout it. Lizzie is essentially playing the movie's theme song, but very badly.
Knowledge of the income of Mr. Bingley and Mr. Darcy is seemingly public and goes unexplained. The value of an estate or an inheritance was usually commonly known among the aristocracy. In the Georgian period it was usual for people to have their inheritance with a bank that gave them an annual interest rate of 4% or 5%. Thus Mr. Darcy inherited £200,000 pounds upon his father's death and now earns £10,000 a year in interest.
Mr. Darcy reveals to Lizzy that his sister is to have 30,000 pounds. This sum is her dowry, given to her upon her marriage from the family. It would amount to an income of 1,500 pounds a year on a 5 percent interest, making Miss Georgiana Darcy a very eligible young woman. In comparison, Mr. Bennet has agreed to give the married Lydia 100 pounds a year, meaning her dowry, as well as those of her four other sisters, is only 2,000 pounds.
The militia uniforms seen in the parade sequence came from the "Sharpe" TV series. There was no unit in the British Infantry at the time with yellow facings on their collars and turn backs, however Bernard Cornwell, author of the Sharpe series created a regiment from whole cloth called the "South Essex" which he described as having yellow facings on their collars. The uniforms were created for the Sharpe's TV series, and were pulled from the wardrobe department for this film.
During Mr. Bingley's private ball, when Miss Bingley and Mr. Darcy are dancing with each other, Miss Bingley says, "I can't help feeling that someone is going to produce a piglet and make us chase it." The song they are dancing to is called "The Tythe Pig."
Joe Wright set the film in 1797 because he disliked the empire-waisted gowns of the late regency era. After doing some research, he discovered that Austen wrote the first draft of the novel in 1797, when this style of dress would only be worn by the most fashionable members of high society.
Pemberley exteriors/Pemberley's grand staircase/Pemberley's sculpture gallery were filmed at Chatsworth House in Derbyshire, England. Chatsworth house has been the family home of the Duke of Devonshire and his family since 1549. In 2008, Keira Knightley would star in The Duchess as Georgiana Cavendish, 5th Duchess of Devonshire.
In the "Official Trailer", the first music heard is from Track 13 of the Sense and Sensibility (1995) soundtrack; later it plays part of Track 2 of the same soundtrack (while the voiceover says "from the beloved author of 'Emma' and 'Sense and Sensibility'"); and later it plays part of the Prime Minister's Love Theme from Love Actually (2003) (while the voiceover says "from the producers of Bridget Jones's Diary (2001) and Love Actually (2003)).
Features five actresses nominated for an Academy Award for Best Actress: Keira Knightley, Rosamund Pike, Brenda Blethyn, Carey Mulligan and Dame Judi Dench. Of these, Keira Knightley and Brenda Blethyn have also been nominated for Best Supporting Actress, while Judi Dench won Best Supporting Actress for her performance as Queen Elizabeth I in Shakespeare in Love (1998)
Keira Knightley stars in several other films directed by Joe Wright, including Atonement (2007) in which she plays Cecilia and Anna Karenina (2012) in which she plays Anna. Dario Marianelli, who composed Pride and Prejudice's soundtrack, also composed the soundtrack for Anna Karenina. Additionally, Matthew MacFadyen appears in Anna Karenina as Stepan Arkadyevich Oblonsky, Anna's brother.
The trivia items below may give away important plot points.
Emma Thompson did an uncredited and unpaid re-write of the script. She receives a "Special Thanks" credit at the end of the film. One of the two scenes that Emma Thompson wrote was the scene in which Charlotte Lucas tells Elizabeth Bennet that she will marry Mr. Collins. The other one is the scene in which Elizabeth Bennet tries to tell Mr. and Mrs. Gardiner and Darcy about Lydia's elopement with Wickham. Here Keira Knightley's walking in and out of the room was Emma Thompson's idea according to Joe Wright's DVD commentary.
The frequent close-ups of Matthew Macfadyen's hand are a reference to the fact that the ultimate goal of the Bennet sisters' lives is a wealthy man's "hand" in marriage, and a foreshadowing of the fact that Elizabeth does in fact eventually win Darcy's "hand".
The almost-kiss during the rain proposal was unique to Matthew Macfadyen playing Darcy. It came up in his screen test with Keira Knightley due to their chemistry with each other, as is stated by the DVD commentary.
