Corrected entry: Throughout the movie you can see macarons, which were not invented until 1792, a year before Marie Antoniette's death.
Corrected entry: In the scene when Marie is trying on shoes and eating all those desserts, she is seen giving her dog desserts. The desserts have chocolate in them, which would kill the dog.
Corrected entry: In the scene by the window, when Marie says 'Oh I love your shoes Victoria', to avoid talking to Madame Du Barry, Victoria says ' Thank you, I got them from Christian in Paris'. This is actually an homage to Christian Louboutin, who designed all of the movies shoes.
Corrected entry: In the marital bed, when Marie indicates she is chilly, and the Dauphin asks if she wishes a blanket, I find it highly unlikely that the phrase, "It's okay," would be used in 18th century France.
