Bridget Jones: The Edge of Reason (2004)

Factual error: Bridget appears to be making her first parachute jump. The mistake is that she would not be permitted under UK law to make her first jump the way she does. She would either have to jump with a static line attached to the aircraft, which opens her parachute automatically. Or if she took an accelerated free fall course, she could free fall but she would do so with two instructors jumping with her to steady her and open her chute if she panicked.

Mark Darcy: Hello?
Bridget Jones: It's me. Just wondered how you are.
Mark Darcy: I'm fine thanks. Everything all right with you?
Bridget Jones: Fine, though, er, I've just had a rather graphic shag flashback. You do have a genuinely gorgeous bottom.
Mark Darcy: Right, well, thank you. I'm actually with the Mexican Ambassador just at the moment and the Head of Amnesty International and the Under Secretary for Trade and Industry and you're on speakerphone.
Bridget Jones: Oh, right.

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).

Question: In the book, Jude marries Vile Richard and Uncle Geoffrey is discovered to be gay and has a 'toy boy'. These are two major story-lines in the book, and to the films, because Jude is Bridget's best friend and Uncle Geoffrey is made out be be a sex/woman mad freak, so why were they dropped? And also, could we therefore see the story-lines in a possible third movie?
