Even though the film is set six weeks after the original in 2001, when Bridget and Mark are travelling in Mark's BMW it has a '53' numberplate which were issued between 1st September 2003 and 28th February 2004.
Back at her workplace following the skydiving fiasco, as Bridget walks to her boss's office her sweater is buttoned the wrong way in one shot, the right way in the next, and back to the wrong way when she actually enters the office.
In the scene with Bridget, Shazzer, Jude and Tom are smoking, and Jude is holding a book with the title, "What Men Want Today" her cigarette changes from her smoking it from her right hand to it being in her mouth as she holds the book up to Bridget.
When Bridget rides to Mark Darcy's house in a Mercedes C-Class taxi, when she arrives at the house the car has different alloy wheels to the ones seen in a previous shot of the taxi driving through the streets. Also when it drives off the beginning of the sequence the car has no model badge (such as C180) on the boot lid, in the next shot (it passes a row of taxis) it does.
In the sequence at the end where Bridget takes a black cab to go to the law chambers (and stops on the way to change her outside), two different cars are used, one with an H-reg numberplate and one with an N-reg numberplate.
It is snowing at the beginning of the skiing sequence when Bridget is seen carrying her skis. However, when she and Mark are on the chairlift there is not a cloud in the sky or any snow falling from it. Its snowing again when Bridget gets mixed up with the skiers who are in some kind of competition.
In the scene on the beach when Bridget is making a sand angel at Daniel's feet, some sort of tarp underneath the sand can be clearly seen being pulled tight between Bridget's legs as they move back and forth.
Bridget says at the beginning of the film, which is at Christmastime, that she has "been in a functional relationship with an adult male for six wonderful weeks," but she actually begins to date Mark Darcy the previous Christmas. This means they have been together for approximately one year.
During the skydiving scene when Bridget is under canopy she is seen holding a Metal D Handle in her right hand. Metal D handles are only used for the reserve parachute, the reserve D handle is still clearly in place on her left webbing. The parachute deployed is clearly a main parachute deployed using a BOC hand deploy pilot chute - not a rip cord.
At Bridget's parents' wedding at the end, Mark and Bridget are seen walking through a graveyard. The gravestones are obviously computer generated because when you look closely, Bridget and Mark walk THROUGH one or two of them.
The video footage coming from the camera strapped to Bridget's head when she is about to jump out of the plane doesn't match her head movements. When her head is seen to nod on the Control Room screen on the left, the footage from the camera on the right screen doesn't nod.
