In “Bridget Jones’s Diary,” Colin Firth plays Mark Darcy, so the surname of his character is Darcy.
The character is a modern romantic-comedy counterpart to Fitzwilliam Darcy from Jane Austen’s “Pride and Prejudice.” That connection is deliberate: Helen Fielding’s novel, and the 2001 film adaptation, use Austen-inspired names and relationship dynamics while placing them in contemporary London.
Mark Darcy is introduced as a reserved, seemingly arrogant barrister who becomes one of Bridget’s principal love interests. Colin Firth’s casting adds another layer because he had previously played Mr. Darcy in the BBC television adaptation of “Pride and Prejudice.”
The other options are Austen-related names, which makes them tempting but incorrect. Wickham, Bingley, and Bennet belong to the wider “Pride and Prejudice” world, whereas Darcy is the surname attached to Firth’s character in the “Bridget Jones” story. The film stars Renée Zellweger as Bridget and Hugh Grant as Daniel Cleaver.
