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. (01:12:20)
Trivia: When Mark Darcy returns from America in order to kiss Bridget, she asks him: "So you're not going to America then?" and he says "So it would seem." Incidentally that is also the last line of the BBC version of Pride and Prejudice, which also starred Colin Firth. Helen Fielding, the author, openly admits that she got her inspiration for the story from Pride and Prejudice. It was written for TV by the same bloke, Andrew Davies, who helped write the screenplay for Bridget Jones's Diary.
Mark Darcy: I don't think you're an idiot at all. I mean, there are elements of the ridiculous about you. Your mother's pretty interesting. And you really are an appallingly bad public speaker. And, um, you tend to let whatever's in your head come out of your mouth without much consideration of the consequences... But the thing is, um, what I'm trying to say, very inarticulately, is that, um, in fact, perhaps despite appearances, I like you, very much. Just as you are.
