Continuity mistake: When Jesse and Celine are walking along, there is a man in a red shirt who is just getting ready to pass them (with the camera shot looking from their backs). The scene shifts to a frontal shot, but the man in the red shirt does not pass immediately as he should have. There is too long of a time gap before he finally appears in the shot and passes Jesse and Celine.
Continuity mistake: Celine is opening her apartment door. The door-handle is on the left side. When they walk in and close the door, the door-handle inside is again on the left side. (01:08:25)
Factual error: Celine and Jesse are walking from Shakespeare & Company on the left bank of Seine to the Pure Cafe on the right bank, but they never cross a bridge.
Continuity mistake: While in the Cafe, behind Jesse there is a woman who receives a rose. The rose disappears and reappears in different places between shots. (00:21:45)
Continuity mistake: Jesse and Celine are sitting on a park bench, and he has his right arm behind Celine on top of the bench. The next shot is a front view and his arm is resting on his leg. (00:40:10)
Visible crew/equipment: While walking to the cafe, once they turn the first close corner you can see the boom microphone at the top of the shot for half a second.
Continuity mistake: In the scene in the cafe, behind Celine there is a man smoking. In one shot he puts out his cigarette, but then from shot to shot he is shown smoking and not smoking several times.
Continuity mistake: While the couple is walking there is a shot from behind which shows them entering a tunnel, in the end of the tunnel there is a grey car parked, once they pass the tunnel you can see by the reflections that the car is gone. (00:16:50)
Continuity mistake: When they are in the van, the background car keep changing from a blue one to a grey one, returning to the blue one in a matter of seconds.
Visible crew/equipment: At Celine's apartment, just as she's dancing and telling Jesse that he's going to miss his plane, a boom mic can be seen at the top right of the shot. (01:17:10)
Continuity mistake: When Celine and Jesse are walking from Shakespeare & Company, the same passers-by appear in every single scene.
Continuity mistake: At the very beginning, Jesse is in a book store during a Q & A sessions with a bunch of readers. In front of him on the table are some books and glasses. The position of the books change between close-up shots of him and further away ones showing the fans. (00:03:00)
