Continuity mistake: At the end Bridget gets drenched, and when she enters the law offices conference room, she is carrying a small purse with her. When Darcy goes out of the room with Bridget however, the purse is not in her hands, though in the background it does look like the pink purse is lying on the table in front of Darcy's empty seat - with no proper continuity explanation as to how it would be there. (01:35:30 - 01:37:20)
Continuity mistake: In the fountain fight towards the end when the camera cuts back and forward, to and from Darcy, his shirt is buttoned differently each time.
Continuity mistake: When Bridget's parents pick her up at the airport and all three are in the elevator, Bridget and her father are both about to take a drag off their cigarettes. In the next shot, the cigarettes are nowhere in sight. (01:22:35)
Continuity mistake: Bridget comes back from the Law Society dinner late at night; it is dark outside. Yet when she comes back home and passes by the stained glass window in her apartment, plenty of light is coming through it. (This shot has been cut from the DVD release.)
Continuity mistake: When Bridget is in the Thailand prison she is taken out of the cell into another caged area to speak with Mark. As she throws her cigarette out of the cell you can see a line of girls being directed into a cell. After a few minutes of talking to Mark, near the end of the line of girls, a guard is standing next to a girl in a skirt with what looks like yellow sleeves. The camera cuts to Mark, then back to Bridget and the girl walks by again. Later in this scene two guards walk past the same spot behind Bridget twice.
Continuity mistake: When Daniel and Mark are talking to each other after fighting in the fountain, the front of Daniel's hair changes in every shot.
Continuity mistake: When Bridget and Mark leave the dinner party at her parents house it is dark and the car headlights are on. When the scene cuts to inside the car where they are talking, it is light outside. Finally an exterior shot shows the car in daylight.
Continuity mistake: When Bridget is on drugs in Thailand, she swims in the water and Daniel Cleaver calls out to her from the sand. The level of wetness on his pants changes, it goes from barely past his ankle to just under his knee and back again.
Continuity mistake: At Bridget's mother's party, Bridget sees her perverted uncle coming toward her, holding a glass of wine in each hand. The shot cuts and as she passes, her uncle grabs her butt. Where did the glass of wine go?
Continuity mistake: In the first movie, Bridget's building is standing mostly alone, with no other buildings very close to it (see the first full shot of it: there's nothing on its sides). Yet in this one, we can see several times that there are a lot of tall buildings all around. Same building, different setting.
Continuity mistake: Before the taxi takes Bridget to one of the Inns of Court, Bridget detours to change her clothes, and the taxi driver gives a thumbs up to a dress with a playful pattern. During the following shots, Bridget wears three different dresses with changes to the pattern, though it is the very same style of dress. It's particularly noticeable when Mark excuses himself, then exits the meeting room with Bridget.
Continuity mistake: The part in the middle of the movie where Bridget Jones is texting Mark Darcy that she already misses him, he walks behind her and says, "I miss you too." She is wearing a grey wool outfit jacket and skirt. But when she gets to the office, she is wearing a black cotton-looking skirt.
Answer: These storylines were probably cut out because they focus on secondary characters other than Bridget, which are usually the first things to go in movie adaptions of novels. Even if they had been included, it wouldn't have been more than a passing mention.
