Continuity mistake: The beginning of the movie is set on Thursday, the day after Jim died, and Bridgette's face was just fine. Later in the movie, on Saturday, Bridgette was at the funeral with cuts and stitches on her face. Then, the movie goes back to Tuesday, the day before Jim died, and they show Bridgette running into the glass door and cutting her face. So if it happened on Tuesday, the first scene of the movie (Thursday) should have shown the cuts on her face.
Continuity mistake: When Linda is writing out the calendar of the order of the events each day, she writes Mon, Tues, Wed. across the top very hurriedly. The second time we see the days, when she writes "Jim alive again", the three days are written differently. The "M" in "Mon" crosses the line below the first time but not the second. The "T" in "Tues" crosses over into the "Mon" column, almost underlining the "Mon". It is much tighter the second time we see it. The "Wed" touches the right side of the column in the first but the left side in the second. Later when she pulls out the calendar again and adds the name Claire, the days of the week are written a third way. Originally the word "Cuts" didn't have an exclamation point but later it does. The word Funeral is first written at the top of the column near the word "Sat" but later it is seen much lower down the column. The phrase "Find out Jim died" is first written very small but in a latter shot it is bigger with the "F" extending into the previous column which it didn't do earlier. It is written a third way when she pulls out the calendar again to add Claire. Apparently the calendar was written at least three times.
Continuity mistake: Sandra Bullock's hair color changes from dark brown with subtle, natural highlights to dark brown with very auburn, reddish highlights. Her hair color changes back and forth throughout the movie.
Continuity mistake: When Linda notices the ripped-out page in the phone book on Saturday, only a very small portion near the spine is left. When she actually rips it out on Tuesday, there's at least a third of the page left.
Continuity mistake: Just after the transformer gets struck by lightning, when Jim and Linda go back into the house, Jim enters the bedroom, you can see a watch on his left hand, but when Jim sits down on the bed, the watch has vanished. (01:20:00 - 01:20:45)
Continuity mistake: When Linda makes the chart of the week, we hear her make 7 vertical strikes, yet in the next shot, there are only 6.
Continuity mistake: In the scene where Sandra's character is looking for the Dr. phone and the page is ripped out of the phone book, she sees it in the trash. When she goes to the trash the phone laying on the table is pointing toward the trash can but when she goes to pick it up it's turned another way.
Continuity mistake: When the psychiatrist is going to sedate her, he moves from her right to her left and back a few times in the same scene.
Continuity mistake: In the scene where she goes in the bathroom and she finds the pills in the sink for the first time, she picks up the medicine bottle but when she sets it back down on the sink the bottle is a different size, it is smaller around than the one she picked up out of the sink.
Continuity mistake: Towards the end when Jim has dropped off his girls at school, he's back on the road when Linda calls him on his cell. This is obviously in the morning but when Jim looks at his phone to see who's calling, the time on the phone says 3:45 pm.
Continuity mistake: Monday (Tuesday?) when Linda is driving down the road, distracted, her passenger side visor is down. When she gets pulled over, she needs to pull the visor down to retrieve her registration.
Continuity mistake: Linda's nightgown Monday morning is not the one she was wearing when she went to sleep Sunday night.
Continuity mistake: The first day she lives through she finds out Jim dies and tells the kids. Her daughter's face isn't cut up when she tells them, but later we find out her face was cut when Jim was still in town. Her face should have been cut up when she found out her dad had died.
Continuity mistake: When the daughter runs through the glass door, it breaks into large pieces. Later when Jim is sweeping it up, it's in much smaller pieces.
Continuity mistake: When Linda is adding Claire's name to the calendar she added it the day before Jim died. (Tuesday). But in her flashback Claire said "I thought that after we spoke yesterday..." She said this at the burial. If the funeral is Saturday that meant that Linda went to her house on Friday. But she put it on Tuesday which is actually when she first met Claire in Jim's office. (01:00:30)
Suggested correction: All of this is correct, but I don't think it really counts as a continuity error. It makes sense that Linda would put Claire's name under the day that they first met. She does the same with Dr. Roth's name. Besides, it's still Friday morning at this point. She hasn't gone to see Claire yet. So far, she's only added to the calendar things that she's already experienced; even if she knew she was going to go see Claire that day (because of the funeral flashback), why would she break the pattern?
