Sofia Coppola refused to read the famous biography of Marie-Antoinette written by Stefan Zweig, which she judged too strict. She turned instead to the book by Antonia Fraser, which makes the queen a more human character, a young girl with no connection to reality who finds herself in the wrong place at the wrong time.
When Marie-Antoinette is going through her shoes while preparing for a big party you see a pair of blue Converse All Star 1923 Chuck Taylor basketball shoes for about one and a half seconds. While these shoes were definitely not in existence at the time of Marie-Antoinette, their inclusion in the film was intentional, to portray Marie-Antoinette as a typical teenage girl despite the time she lived in.
Sofia Coppola discovered in 2000 the Marie-Antoinette biography by French historian Evelyne Lever, acquired the book rights and asked its author to accompany her on a first tour of Versailles in 2001. Coppola later turned to the queen biography written by Antonia Fraser, more popular in the United States. Lever was later asked to work as an historical consultant for the movie, writing a dossier on the queen in order to avoid mistakes and approximations.
A few quotes from the film are directly taken from Marie Antoinette's actual life and from the biography by Lady Antonia Fraser that the film is loosely based upon. Louis XV's comment about Marie Antoinette's bosom upon her arrival in France, Marie Antoinette's comment on having enough diamonds when presented with the opportunity of receiving some as a gift from Madame du Barry, Marie's comment to Madame du Barry about there being a lot of people at Versailles on the day of their infamous first exchange of words, and Marie's comment to her husband, Louis XVI, during a gambling party, explaining that Louis told her she could throw the party but never specified for how long are all actual exchanges of words and conversations from different events in the queen's life.
Joseph II may seem like an odd choice to teach Louis XVI about reproduction. All of Joseph's known children died in childhood, and he apparently never reproduced for the last 27 years of his life. He could, however, afford to rest on the laurels of his brother and heir-presumptive Leopold II, who had many children including Franz II (powerful rival and ally of Napoléon Bonaparte). This being said, the scene is still based on historical evidence. Joseph visited Marie Antoinette in 1777 and, in a letter to his brother, boasted about his lesson to Louis. In 1778 their daughter Marie Thérèse Charlotte was born.
This movie was going to be produced before Lost in Translation (2003), but while Sofia Coppola was writing the screenplay struggling with historical truth and an imposing gallery of characters, she started creating another story in order to distract herself from the difficult enterprise. This parallel project - a small Japanese story - became "Lost in Translation", whose planetary success revamped the Marie-Antoinette production.
Marianne Faithfull's mother, Eva von Sacher-Masoch, Baroness Erisso, was originally from Vienna, Austria, with aristocratic roots in the Habsburg Dynasty. In the movie, Marianne Faithfull plays Empress Maria Theresa, a member of the Habsburg Dynasty and ruler of the Austrian lands.
The part of Louis XV was first offered to Alain Delon. Allegedly, he met Sofia Coppola for dinner and brought the American director a huge bouquet of flowers and explained he did not think this was the type of role his fans would appreciate him in. Privately it has been speculated the French icon did not have confidence in the young American director to do justice to a film on this period of French history.
Even though the Hall of Mirrors at the Palace of Versailles was in restoration - until spring 2007 - Sofia Coppola was allowed to film there a ball scene for the wedding of Marie-Antoinette and Louis XVI.
According to some history accounts, when Marie Antoinette met the rioters on the balcony of the palace, she had her eldest daughter with her. This was supposedly in order to augment a sense of sympathy for the doomed queen.
The trivia item below may give away important plot points.
There is a scene toward the end of the movie which shows many princes and princesses of the blood saying farewell to the Queen before fleeing the country, including her two favorite companions, the Duchesse de Polignac and the Princesse de Lamballe. The real Duchesse de Polignac did take refuge in Switzerland. Princesse de Lamballe did initially leave the royal family for safety in England, but returned later at the request of Marie Antoinette after she and her family were caught trying to escape. She remained with the royal family until her own arrest; after refusing to sign an oath renouncing the monarchy, she was mutilated and beheaded, and her head was mounted on a pike and paraded past the prison window of the doomed Queen.
