Plot hole: In Pemberley, Caroline Bingley refers to an utterance of Darcy ("I should as soon call her mother a wit") that he made after coming home to Netherfield after their first ball in Meryton. Falsely she says he made this expression "after they had been dining at Netherfield". This is a direct quotation from the novel and is not coherent with the film plot in which this utterance is made after the first ball.
