Continuity mistake: When Steve McQueen is removing his fire suit in the elevator, his tie is loose. But when he runs into the promenade room right afterwards, his tie is secured by a tie clip.
Suggested correction: He has a tie clip the entire time. As he removes his jacket before entering the promenade room, you can briefly see the clip.
Continuity mistake: In the early part of the TV version. They are holding a meeting in Mr.Bigelows' office regarding Romane Conti. He asked a gentleman from Phoenix on the phone if he could get the wine. Then told his assistant "go get it". A flight plan would have to be filed,and the flying time from SFO to PHX is about 2 hours. Then to find the place where he has to get the Romane Conti. I lived in the Phoenix area for almost 13 years and it is spread out. Then get back to the airport,another 2 hour flight. I would say the fire department would have gotten there first.
Suggested correction: During this meeting, his assistant has already picked up the Romane Conti. The meeting they had about picking this up was much earlier in the day. Plenty of time for him to leave and come back before the fire begins.
Character mistake: Just before the fire starts on the 81st floor, a man is shown telling an elderly couple that business offices only go as high as 80, and that 81-120 is exclusively residential. Not long after O'Hallorhan arrives, he asks Jernigan for a list of business tenants from 81-85, which Jernigan replies "most are yet to move in and those that have are not working at night". As said by the man earlier, these floors do not house business tenants, only residential. (00:12:05 - 00:43:45)
Suggested correction: Chief O'Halloran asked Doug for the floor plans from 81-85. He then asked Jernigan for a list of business tenants. Chief O'Halloran did not ask for businesses on any specific floor.
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.
Suggested correction: He has the flowers with him the entire time, from the cab ride to entering the hotel. You can see them when he pays the cabbie and when he's going to the hotel. He's carrying the flowers and the box in the same hand.
