Revealing mistake: In the first scene when Bridget makes her way up her parent's driveway, you can see her shadow against the cobbled post. However, the sun isn't out and it's cloudy, cold weather overhead. (00:01:15)
Visible crew/equipment: During the scene when Bridget and Cleaver are talking about Lara in his office you can see the film crew moving about in the reflection of the glass walls (and presumably the director sitting in a chair). This cannot be office workers as his office is raised from ground level. (00:45:05)
Continuity mistake: When Mark returns from the States, as he begins to kiss Bridget for the first time, from the camera shot behind him, his head is angled to the right. From the shot behind Bridget, it is angled to the left.
Continuity mistake: When Bridget has been invited to the dinner party (the one with all the couples) she has a drink - to start with it is two thirds full, next shot half full - she hasn't drunk any because she is talking next scene and it's two thirds full again.
Continuity mistake: When Bridget writes her diary on 1st January, we see the fridge in the background at floor level, alongside other kitchen units. But later, just after Daniel has announced his engagement to Lara, Bridget opens the fridge to "eat the entire contents" - the fridge is now on the sideboard, with no units beside it, also its decorations are different. Later when Bridget is cooking, she opens the fridge and looks in - she is crouching in front of it, as if it is at floor level again. (00:07:36)
Continuity mistake: When her mother comes back home, the camera switches between a view of her Mum where you can see the back of her Dad's head, and the reverse shot. When she's saying "you must pay more attention to me", after she says "me" her mouth is open when you see the back of her head, but after it switches and we see her from the front, her mouth's shut.
