Trivia: In the scene where Bridget and Shazzer are on the plane to Thailand, where Shazzer first meets Jed, both she and Jed are reading "The Beach" by Alex Garland, a book about young travellers in Thailand. One of the main characters in the book is also called 'Jed' and many of the scenes featured in the film are mentioned in this book (such as drug trafficking, transsexual Thai prostitutes, etc).
Trivia: In the film, when Bridget has broken up from Darcy, she is telling someone that she wishes he would turn up at her door, preferably dressed in a wet white shirt. This is a reference to when Colin Firth played Mr. Darcy in "Pride and Prejudice" (1995), and the shot of him emerging from a swim wearing a flappy wet white shirt made him a massive sex icon to women in their mid-thirties.
Trivia: In the scene where Bridget and Mark are in the conservatory talking to her parents, the leaves in the background outside do not move at all. On the DVD extras, the editor explains why this happens - she simply forgot to use a wind machine to make it look more lifelike.
