Continuity mistake: When the first woman goes across on the breeches buoy, the overhead shot of her going across does not show the outside elevator which at this stage is hanging by a cable and stuck on the outside. However, it is visible in the shots from the peerless building which the breeches buoy is attached to. (02:05:10)
Continuity mistake: In the shot where the 12 people are going down the scenic elevator, you can see the fire coming through the windows but then, when it widens out the shot to show the helicopter flying nearby, there are no flames whatsoever on any floor of the building. (01:57:35)
Factual error: When the fire department first arrived, they should have had the utility provider shut off the gas lines to avoid just the type of explosions that happened continually throughout the movie.
Continuity mistake: When Fred Astaire leaves the cab he doesn't have anything in his hand with the box, but as he walks to the hotel he has a small bunch of flowers which he takes into the hotel with him. But they are never seen again. He does not give them to his date, nor does have a flower in his buttonhole.
