Pride and Prejudice
Abigail Reynolds is the author of seven Regency-set variations on "Pride and Prejudice".

Her modern adaptation, "The Man Who Loved Pride and Prejudice", is set on Cape Cod.
Bridget Jones: The Edge of Reason
Much is made of Bridget's fascination with the BBC television adaptation of "Pride and Prejudice" and Colin Firth, the actor who played Mr. Darcy. Bridget even meets Colin Firth and interviews him for a newspaper article. As a self-referential in-joke, Colin Firth plays Mark Darcy in both Bridget Jones movies.
