Factual error: It is absolutely impossible that the fire suppression system would still be operational at the end of the film. The fire would have destroyed all those systems ages ago, and even if the extinguishers / sprinklers themselves are resistant to fire, I doubt very much the cables that hook them up to the building's computer system survived intact.
Skyscraper (2018)
1 factual error
Directed by: Rawson Marshall Thurber
Starring: Dwayne Johnson, Neve Campbell, Noah Taylor, Pablo Schreiber
Other mistake: A police helicopter nearly crashes and has to veer away because of the superheated air around the building when only a few floors are on fire, but Will Sawyer and everyone else can function normally when half the building is ablaze. In fact, everyone barely breaks a sweat despite being surrounded by flames.
Will Sawyer: I love you.
Sarah Sawyer: You'd better.
