Starring: Colin Firth, Jennifer Ehle, Julia Sawalha, Susannah Harker
Audio problem: While Maria is singing "God Rest Ye Merry Gentlemen" accompanied by Mary Bennett, the movement of her lips is out of synch with the audio track.
Audio problem: When Lizzy, her aunt and uncle are in the tavern dining room discussing whether or not they should visit Pemberley, pay very close attention when Lizzy says, "We've no business there." The pitch and tone of the voice sounds completely different than Jennifer Ehle's. It sounds like it was dubbed.
Episode #1.6 - S1-E6
Visible crew/equipment: When Lady Catherine de Bourgh and Lizzie are by the carriage (right after Lady Catherine de Bourgh questions whether Lizzie is engaged to Mr. Darcy), there's a camera or some sort of device visible. (00:36:40)
Suggested correction: The device being referred to looks like a lamp, which is part of the carriage. Therefore, it is not a mistake.
Mrs. Bennet: You don't know what I suffer.
Trivia: The exterior shots of Pemberley were filmed outside Lyme Park, in Cheshire.
Episode #1.3 - S1-E3
Question: When the Gardiners arrive at Longbourn for Christmas, where are their children? Surely, they would not have travelled without their children at Christmas.
Answer: The children were probably left with a nanny or relatives. It's very likely that the Longborns would have left them at home. Travelling for days by horse-drawn carriage over bumpy dirt roads is difficult in the best of circumstances, and particularly hard during winter. The trip would be too arduous for young children.
