Corrected entry: When Sara is running through Chinatown during heavy rain, she is wearing a blouse that exposes her belly button. However, in the scene right before in which she sees her fiance perform, her blouse covers those areas. (00:33:20)
Corrected entry: When Sarah is returning to SF on a 747, she produces a wallet to fork over the money for a movie. She discovers that she's switched identical wallets with her friend (creating a key plot moment)... but how did she get on the airplane without her own identification, which is inside her own wallet? (01:12:30)
Corrected entry: Toward the end of the film, in Central Park, Sarah looks up in the night sky, sees the constellation Cassiopeia and realizes Jonathan is her man. But unless there's a blackout, stars are not visible in New York City. The city lights blot them out completely.
Corrected entry: When Kate Beckinsale is running through the rain and stops for a cigarette next to the Cool Hand Luke poster, watch her mouth closely. She takes out a cigarette, lights a match, and as she brings the match up she clearly blows it out, then acts annoyed, like the wind did it. (00:34:50)
Corrected entry: In the scene where Jonathan is lying in the middle of the rink, there is a shot of his face as he looks up and sees Sara. The rink around him is covered in snow. There is a long shot of him as he stands up, and there is no snow whatsoever.
Corrected entry: In the final scene, Jonathan lies his head on Sara's jacket in the middle of the skating rink. But when he stands up after catching the glove and turns and sees her, the jacket is gone.
Corrected entry: The actual average "shelf life" of a piece of U.S. paper currency is about 18 months. But the action in this movie is supposed to take place over a few years. During that time, the $5.00 bill with Jon's name and number on it almost certainly would have been pulled from circulation and destroyed due to normal wear and tear; in fact, if it ended up in a bank's inventory and the "mutilation" were discovered, it almost certainly would have been pulled even sooner.
Corrected entry: In the first flight scene, we see Eve and Sara taking off from San Francisco to go to New York city in a DC-9. A DC-9 has a range of about 1000 miles, which wouldn't even get half way across the country without running out of fuel.
Corrected entry: The constellation Cassiopeia is not over New York city all year round. In the movie it is shown both in Spring and Winter.
