Visible crew/equipment: In "Whenever You're Away From Me", Kira and Danny dance by a mirror, where you can see the cameraman. (00:32:10)
Continuity mistake: At the beginning "Pete" asks Violet for her autograph on a time card. She signs it and the "T" is not crossed, and when Pete puts it on the board it is crossed. Then at the end when Violet's dad buys it from Pete it is again not crossed. Also if you look at the "V" when she signs it and after Pete puts it up they are different. And lastly, when Violet signs her last name it is spaced but when Pete puts it up it is jumbled together. Her signature is different all around. (00:01:30 - 01:27:30)
Continuity mistake: During the scene when Thomas Crown is sailing, you can see the weather change from very dark and stormy, to just cloudy, to blue sky and sun, depending on the shot. (00:36:30)

Continuity mistake: When Samuel looks at the handgun in the drawer, the gun is vertical in closeup, but the grip is tilted left when Samuel reaches for it. (00:46:20)

Continuity mistake: When Nino goes to 'Les deux Moulins' for the first time, we can see Amelie writing the menu on a glass right behind him. A few shots later, we see the glass again and the handwriting is quite different. That's easy to see if you look carefully at the 'd'. Later on, we see the glass once more, and the handwriting has changed again. (01:32:55)
Continuity mistake: Mr. Svenning's junior college class ring mysteriously jumps from his left hand to his right hand just in time to get stink-palmed by Brodie.

Revealing mistake: In the final scene when Annie and Sam are exiting the observation deck coming towards the elevators, the New York skyline backdrop which should be visible behind them is missing, and the entire sound stage wall can be seen beyond the observation deck safety railings instead. 'Although the exterior and lobby of the Empire State Building, 350 Fifth Avenue at 34th Street, are the real thing, a slightly larger replica of the Observation Deck was built in a hangar at Sand Point Naval Base on Puget Sound just northeast of - where else? - Seattle.' https://www.movie-locations.com/movies/s/Sleepless-In-Seattle.php. (01:39:35)
Continuity mistake: When "Charlie" is first introduced to the class, she struts down the aisle in heels. When she follows Maverick into the building, you can briefly see that she is wearing flats to compensate for Maverick's short stature. (00:26:00 - 00:28:50)
Revealing mistake: During the scene where Arnold's character is escaping from the mansion at the beginning of the movie, there is a part where he is running down a snowy hill through trees. At one point during the hill scene, Arnold does a flip head first. When he lands the flip, you can clearly see the stunt double's face as he turns to shoot at more bad guys. (00:13:30)
