Corrected entry: When Kate is on the top of the roof with Leopold eating dinner, Kate talks about Prince Charles and Lady Diana. Leopold replies to her something about Prince Charles and Lady Di. How could he know she was called Lady Di?
Corrected entry: When the elevators break down, since they never existed, wouldn't everyone mentally forget about elevators?
Correction: This is done as a mere shadow of the way that Stuart has influenced history. Ripples, as it were, in the pond of time rather than the actual splash. Since Leopold does in fact go back and invent the elevator, they would then exist in the future. When dealing with time travel, just because an event hasn't happened yet doesn't mean that it's effects haven't already happened. It's the same reason why Kate shows up in Stuart's photos in the present before she goes back to the past.
Corrected entry: At the presentation for Kate's promotion at the end, Kate's blue dress has no lace trim at the cleavage, but when she goes back to Leopold's time, it has lace lining the top of the dress.
Correction: The reason Kate's dress has lace on it after she has gone back in time is because her dress changes to fit into the period. If you look closly the back of her dress has also suddenly gained a large train as well.
Corrected entry: In the movie, Leopold's last name is 'Mountbatten'. This is impossible, since the original name - 'Battenberg' - was only changed in 1917 by the British Royal Family, into 'Mountbatten'. This is the result of anti-German feelings during the First World War. Consequently, Leopold's last name should have been 'Battenberg', not 'Mountbatten'.
Corrected entry: Leopold reveals what an ignoramus Kate's boss is by discussing and quoting from La Boheme. But Leopold was brought forward in time from 1876 - 20 years before La Boheme even premiered. (01:01:10)
Correction: Who's to say that Leopold might not have learned that sometime after he'd come into the present time, say from books in Stewart's flat?
Corrected entry: To sample ink for his quill-written letter to Kate, Leopold empties out ballpoint pens, whose ink is much to viscous to flow out as easily as it's shown in this scene. (01:01:05)
Correction: It may have been possible for Leopold to empty ink out of ballpoint pens, since some brands of ballpoint ink become more viscous when heated in hot water or possibly in the microwave oven.
Corrected entry: In the scene where Leopold gives chase on the horse, where did the saddle and stirrups come from? The horse was pulling a carriage. (00:46:50)
Correction: Carriage tack routinely includes a _small_ saddle with stirrups. It's both part of the look and was actually used when gooms would ride at the front of large teams of horses to help control them. In the scene where Leopold pulls Kate onto the horse, you can see the large expanse of blanket behid him that indicates that he is indeed using a small housen, or carriage saddle.

Corrected entry: In the movie the point is made that it is time travel, meaning that you will end up at the same place, just at a different time. So if you jump off a bridge ending up in a different time, you should still fall into the water and not on dry land.
Correction: The time portal is close to the pillar which stands on the ground.
Corrected entry: At the very beginning credits where they are showing the bridge it is very obviously a backdrop. Look closely and you can see the towers with smoke, and the smoke stays still the whole time. (00:00:55)
Correction: The stacks are smoking quite naturally.
Corrected entry: In the opening bridge scene the spectators are waiving 49 star flags in 1876. (00:00:50)
Correction: The flags have 37 stars, 2 rows of 8 and 3 rows of 7.
Corrected entry: Kate's ex-boyfriend has a bad fall down an elevator shaft, because ostensibly time has been altered and Leopold doesn't invent the elevator. But if that's the case, why would the sliding doors to the elevator even be there in the absence of the device they were installed for? He would have just walked into a blank wall.
Correction: Because Leo was in danger of not returning, the elevators were malfunctioning. That is why Stuart fell. The elevators did not disappear from existence. (Notice everyone still knew what elevators were, and some in the city did function properly).
Corrected entry: At the end of the movie, when Leopold comes back to the past, he returns to the same day but earlier in time (we see him going upstairs to prepare for the evening party). Shouldn't he have encounted his earlier self, the Leopold who will later chase Stuart and travel to the present, as was shown in the beginning of the movie?
Correction: This movie apparently has different rules for time travel than the Back to the Future movies, in which multiple selves is a common occurance. For the purpose of this movie, there apparently is only one of each of us parading around in different time periods.
Corrected entry: When all the elevators disappeared, the NY City skyline should have changed also. Surely nobody would build office buildings much higher than 10 stories (the 1890 record) if workers had to walk all the way to the top every day.
Correction: The elevators didn't disappear. Leopold was in jeopardy of not going back in the time, but that fate wasn't 'for sure.' The elevators were not working all over town, just showing how his disappearance from the past could alter the future.
Corrected entry: When Stuart falls down the elevator shaft, the sliding doors to the elevator open when the car was stopped below. Elevator doors are designed to not open unless the car is at that floor or forced open.
Correction: When the "time window" opens, all elevators in Manhattan go crazy. Kate has no elevator at the office and so on. They don't explain why this happen (maybe something to do with Otis), but there's a reason why the door opened without a car.
Corrected entry: Towards the end of the film, when Leopold has already gone back to the past, they show the pictures that Stewart took. Kate is in one of them. But Kate didn't arrive in the past till the point where Leopold is announcing his new wife, and he does this after Stewart left, so there is no way Kate could have been in the picture.
Correction: In the directors cut, you see Kate in the beginning of the film, 'back' in time. She was there the same time Stewart was.
Corrected entry: When Leopold comes to the future the elevators stop working correctly (JJ makes a comment about moving his office to the ground floor due to the malfunctions, people are taking the stairs), yet Kate gets in the elevator near the end of the movie without even thinking about it.
Correction: When Kate gets into the elevator, Leopold has already gone back to 1876, therefore, the elevators are no longer malfunctioning.
The elevator just broke it had nothing to do with whether he was there or not. If that were the case there wouldn't be an elevator in the first place.
Correction: Kate actually does not say "Lady Diana", she says "Lady Di". This is how Leopold knew to call her that.
