Corrected entry: When Mr Collins proposes to Lizzie, you can see a bright rectangular light through the passageway used by Lizzie and Kitty to enter the room. You see it as they enter the room above Lizzie's head, and again as Kitty and Mrs. Bennett leave the room. (01:34:25 - 01:35:05)
Corrected entry: The corsetry is completely wrong in this movie. Even a cursory examination of period fashion plates and portraiture shows that cleavage was "out," and the corset provided the most minimal support possible for the bust, or not at all. Fashion plates show the Regency waistline around the ribcage naturally just below the bust; but the movie's corsetry holds this line out from the body, completely changing the silhouette.
Corrected entry: The music room in Pemberley is supposed to be on the ground floor as shown by the housekeeper, when Elizabeth first gets to the place with her aunt and uncle. When Darcy goes back to the music room after Elizabeth's first evening with him and his family, he walks along the portrait gallery which is supposed to be on the first floor (as shown by the housekeeper), so in this scene the music room is on the first floor.
Corrected entry: When Lizzie and Charlotte Lucas return home from their visit to Rosings Park, they are riding in a public stagecoach. But in both the text (Ch. 37-38) and the movie dialogue, they travel post, which is a completely different thing. A post-chaise, even if hired, is private; on the stage coach (which is not a chaise), the young ladies must share the interior of the coach with strangers. This was not done by ladies of their class except in extraordinary circumstances, none of which are mentioned in the text or the movie dialogue.
Corrected entry: When Lizzie is singing and playing for Mr. Darcy, Mr Bingley, and the sisters at Pemberley the music sounds like a harpsichord. After Lizzie has finished she persuades Georgiana to play for everyone. Georgiana sits at the same instrument as Lizzie and starts playing, only this time the music is a piano, not harpsichord.
Corrected entry: In the final scene, when they're all married and happy and ride off in the coaches, Lizzie and Darcy get in, and the coach starts to move. The camera then switches to Mr. and Mrs. Bennet, who say something like:" God has been very good to us." "Yes, so it will seem." You can see the carriage riding off, but when the camera moves to close up for the kiss, you can still see in the background the walls of Longbourn, though they've already passed the house.
Corrected entry: In the scene where Mary Bennet tries to show off and is followed by Caroline Bingley, Caroline plays a piece by Mendelssohn, who was born in 1807. However, Pride and Prejudice was published in 1813, and set at about that time. Mendelssohn would have had to have written that piece (can't recall the name) at age 6.
