Continuity mistake: When Bridget is getting dressed for her big date with Daniel, her tights are over her undies; later, when he's going up her skirt, the tights are clearly under her big ugly undies.
Visible crew/equipment: When Bridget and Daniel are in the convertible going to the country for the weekend, her scarf flies off. If you look carefully in the wide shot, you can see a crew member's hand in the backseat pulling it off and then tossing the scarf to the back of the convertible to fly away.
Continuity mistake: After Mark Darcy and Daniel Cleaver fight in the street and Bridget goes to comfort Cleaver, Mark Darcy flings his jacket over his shoulder as he walks off. You can see very clearly that the white lining of the sleeve, flapping around as he walks. When the camera cuts to his receding back, the jacket is perfectly flat and smooth down his back, and the lining is no where to be seen.
Continuity mistake: Tom is changing the fascia of his mobile phone. When we first see him, he is holding the phone up to his shirt and the fascia is blue, he then puts the phone down near to Bridget. It then cuts back to Tom and the phone has moved nearer to Jude and the fascia is green. Tom then opens the box in front of him and hold the blue fascia up so it falls out of the plastic wrapping completely, just before a man comes up to ask him if 'he's the bloke who sang that song' he is getting the blue fascia out of the plastic wrapping again.
Factual error: After all the running about at the end in the snow, no one's breath seems to be condensing.
Continuity mistake: When Shazzer talks about introducing people with thoughtful details, Jude taps off her cigarette ash. Seconds later, she's seen with at least half an inch of ash on her cigarette.
Revealing mistake: When they're driving back to the Darcys' in the snow, you can see that as they pass through the village near the house, the snow on the ground is in fact a white ground sheet and has not been pulled up to the edges of the wall surrounding the green.
Other mistake: When Bridget goes to chase after Mark when he leaves her flat to go and get another diary, she runs out only wearing a tank top and underwear. When she exits the door, she steps into the outside where it's snowing & she's barefoot & she immediately comes back inside to put on shoes. In the beginning part of the movie, we see that she lives in an apartment building where she actually has to ring the people inside & that her door is actually upstairs where she wouldn't step "outside" immediately exiting her flat.
Continuity mistake: When Bridget and Mark prepare the blue soup, Mark stirs the soup with his right hand. In the close-up you can see a left thumb holding the spoon.
Continuity mistake: After Bridget has given the appalling introduction to Mr. Fitzherbet, he comes on stage with the author. Mr. Fitzherbet says "I'll just switch this on" and turns the microphone on, but his voice is being transmitted over the mike before he flicks the switch
Factual error: When Bridget is walking to work (this occurs twice in the film, where I noticed the mistake) she goes through Piccadilly Circus. The next frames show her crossing Tower Bridge, as if it was just over the road. As anyone familiar with London will know, this could take the better part of an hour to walk this far.
Continuity mistake: Mark Darcy is in Bridget's flat and he notices the diary under a folded newspaper and some magazines. In this front shot, he puts the magazines down next to the newspaper and pulls the diary out from under the newspaper. In the next close-up looking down at the table when he holds the diary, the folded newspaper is no longer there. When Bridget walks into the room after Mark leaves, in this front shot of the table, the newspaper is under the diary that Mark had put down. When Bridget comes back from the window, in the close-up looking down at the table, once again the newspaper is not under the diary.
Continuity mistake: After Bridget has chased Mark Darcy in the snow, when the scene initially focuses on Bridget, she has some large concrete barriers behind her, they suddenly disappear from the scene after awhile, just before the big kiss.
Continuity mistake: When Bridget is making her resolutions, she says, 'Put last night's knickers in the laundry basket.' But if you read her diary as she's writing in it, she doesn't mention this resolution, it says 'Lose 30 pounds,' then goes on to the third resolution.
Continuity mistake: When Bridget is quitting her job and Daniel is trying to convince her to stay, you can see a woman behind him, hanging at the door of his office. She's already half inside, but there was no other person in Daniel's office apart from him and Bridget, and she wasn't seen coming into the office.
Continuity mistake: In the shot where Bridget goes to see her mom when the mother is selling the egg separator, her sweatshirt strings are crossed, when the shot cuts to her again they are crossed the other way. After the demonstration, when she is talking with her mother, they are back the same way again.
Continuity mistake: When Bridget and Daniel have gone back to his apartment and they are kissing on the floor and he discovers her enormous panties, she is trying to keep him from checking them out again. In one shot the strap of her dress is up over her shoulder, then it's down off her shoulder, then back up again.
Continuity mistake: When Bridget's boss at the TV show tells her he wants her to cover the Kafir/Heeney case (the freedom fighter), Bridget is playing with her pen over her right shoulder. The shot then shows her boss is talking to her, but neither her hand nor pen are up - in the next angle of her, she is still waving her pen up by her right shoulder.
Continuity mistake: When Mark and Daniel are having their big fight, Mark punches Daniel really hard, causing him to fall to the ground. In the shot of the punch Daniel falls face down towards the ground, however in the next shot he lands flat on his back. It would've been impossible for him to have turned around-especially being knocked out.
