Continuity mistake: After Kathleen (Meg Ryan) and Joe (Tom Hanks) talked about what it would have been like if they hadn't been enemies in the book business, Kathleen says she has to go and heads off to her apartment. During this time, the camera switches back and forth between Joe and Kathleen. Kathleen's right sweater sleeve cuff is by her wrist in one shot and rolled up by her elbow in the next. In the next shot it goes back down again. (01:47:20)
Revealing mistake: Just after they dump the tacks out of the window, the Russians' car flies up into the air in a really quite impressive car crash. Just before it flips over though, you can see the huge ramp put in front of it. (00:32:20)

Continuity mistake: When Blade gets captured and stabbed in the room where the "Vampire Bible" is, he is not wearing an ear piece. In the next shot, he is. (00:51:45)

Revealing mistake: When Puffy the dog bites Ted and pulls him along, Ted digs his fingernails into the floor, they scrape along, making marks. If you look very closely you can see faint pre-made marks made in the floor, where he drags his nails along. (01:28:45)
Continuity mistake: The heels on Barbara's shoes appear and disappear throughout the movie.
Continuity mistake: After Chris is dead, and his wife is writing in her diary, and she writes "I still exist" as she's writing it, exist is written "EXST", then when she looks to read what she wrote it reads "EXT". The writing's different too. (00:22:10)
Continuity mistake: In the flashback, where Victor's parents ask him who his favourite Indian is, before he walks out the door, there are two girls on the porch playing with a sparkler while leaning on the rail, facing away from the door. In the next shot, in a close-up where Victor comes through the door, the girls are now leaning against the exterior of the house next to the door, facing each other. No sparkler in sight. (00:25:11)

Continuity mistake: Annie Girardot and Murray Head are playing with the cake dough and playfully hit and splatter each other. Between the various takes, Annie Girardot gets some cleaning done, because she had hair and coat all messy midway through, but is much cleaner when that part of the scene is a wrap and the story moves on; the hair (she had an egg cracked on her head) is fine and the coat that had streaks of cream on the lapel is almost spotless. (00:25:20)
Deliberate mistake: While Laurence is driving to the park trying to find Martha there are closeups of his car en route, and one of the closeups of the front left side of his car is a flipped shot, note the backwards "Saab" and the surface damage which is actually at the right side of his car. (00:56:00)
