Anna Chancellor (Miss Bingley) is actually related to Jane Austen. Chancellor is a direct descendant of Austen's elder brother, Edward.

Jennifer Ehle and Colin Firth had a romantic relationship after meeting while filming the series.

The most famous moment of the series, the lake scene, was not part of Austen's novel. Andrew Davies wrote the scene not because he wanted a sexual connection between Elizabeth and Darcy but to create "an amusing moment in which Darcy tries to maintain his dignity while improperly dressed and sopping wet."

Casting the role of Darcy's young sister, Georgiana, proved hard as the producers were looking for a young actress who appeared innocent, proud and yet shy, had class and could also play the piano. After auditioning over 70 actresses, Simon Langton suggested Emilia Fox, the real-life daughter of Joanna David (Mrs Gardiner), for the part.

Sue Birtwistle particularly wanted Colin Firth, a relatively unknown British actor in his mid-30s at the time, to play the wealthy and aloof Mr. Darcy. Birtwistle had worked with him on the mid-1980s comedy film "Dutch Girls," but he repeatedly turned down her offer as he neither felt attracted to Austen's feminine perspective nor believed himself to be right for the role. Birtwistle's persistent coaxing and his deeper looks into the Darcy character finally convinced him to accept the role.
