Continuity: When Mr Darcy confesses his love for Elizabeth, both characters' fringes change position throughout the confrontation.
Audio/visual unsynchronized: When Mrs. Bennet's sister comes, delivering Jane from London, Kitty comes into the room crying. When Mrs. Bennet's sister says, "They probably can't afford it," her mouth is still moving after the line has ended.
Crew or equipment visible: During the ballroom scene, when Lizzie and Charlotte bump into Mr Darcy and he asks Lizzie to dance with him, if you turn the volume up you can hear the crew members discussing the position of the boom in the background.
Continuity: At the dinner in Lady Catherine's house, the second candle from the left on the candle holder is alternately crooked/straight during Elizabeth and Lady Catherine's conversation.
Continuity: During the second dance that Jane is dancing in, Mr. Darcy changes his position near the fireplace many times between shots.
Incorrectly regarded as goofs: In the Netherfield Hall ballroom scene, Mary is seen behind Mr. Collins when Mr. Collins loudly introduces himself to Mr. Darcy; she is then immediately heard playing the piano in the next room. The director, Joe Wright accounts for this in the DVD commentary, where he states that this scene is the start of a montage of the events that occur at the ball, but was shot as one continuous shot.
Revealing mistakes: During the first scene of the movie in the house when Mary is seen playing the piano, she is not actually touching the keys.
Anachronisms: Pianos in the 18th century didn't sound like modern pianos.
Anachronisms: On the green outside the Collin's Rectory is a cenotaph of a type which did not come into use until the 20th Century.
Anachronisms: Lizzie is clearly wearing Wellington boots in many scenes.
Audio/visual unsynchronized: In the scene where Jane tells Elizabeth that Mr. Wickham has not come to the ball, Jane's lips keep moving after Elizabeth says "He must be here," though Jane says nothing.
Incorrectly regarded as goofs: At the very beginning of the movie, the sun is half way up in the sky, as though early morning, yet when they show Mary playing inside Longbourn, it is low in the sky as though late in the afternoon. In the commentary the director explains that the change in the lighting is meant to indicate the passing of time.
Revealing mistakes: In the scene where Elizabeth examines the bust of Mr. Darcy, the camera pans around the back of the bust and dried dollops of plaster can be clearly seen on the backside of the shoulders and the column. The bust is supposed to be carved marble, and would not have the plaster dollops.
Factual errors: As this story is based in 1797 the people watching the military parade are waving the union flag of union between Scotland and England, but the military are clearly carrying the union flag of 1801, when the cross of St Patrick was introduced as Ireland was brought into the union.
Continuity: Towards the end of the movie, when Lizzie wakes up to walk outside, her hair is on the outside of her jacket. Once she starts to talk to Mr. Darcy, her hair is tucked into her jacket.
Continuity: While sitting in the woods "quite close to" Mr Darcy's house with her Aunt and Uncle, Lizzie is wearing a dark brown dress with a lighter colored coat. But when they go to see the house, Lizzie's dress has changed to a cream striped dress with the same coat as before.
Continuity: When Mr. Darcy helps Lizzie into the carriage, the hand shot shows her in the process of sitting down, but the next cut shows her still standing.
Continuity: Early in the film Darcy assists Elizabeth into the carriage with this right hand. Afterwards the camera zooms onto this hand to show the effect that this 'first touch' has upon him. In a much later part of the film when Darcy wants to touch her again, but cannot, the camera zooms on this hand again. This time, however, it is his left hand.
