Corrected entry: The opening of the film is set in 1971 and when we see a young Kurt Russell (flipping off his brother), he looks to be about 6 or 7. The film then fast forwards 20 years later (1991) and Kurt Russell is looking all of his then 40 years. Certainly not someone in his mid to late 20's.
Corrected entry: In any scene where they are fighting fire inside of a building, there is no smoke. Any type of fire will produce large amounts of smoke.
Corrected entry: In the final scene in the chemical factory, Brian takes a fire extinguisher and breaks the "head" off and throws it into the blaze thus causing the fire to blow itself out. This is impossible.. With the pressure of the extinguisher if he were to break the head off it would either blow up right then or send him flying from the pressure about 50 yards.
Corrected entry: When Brian visits Stephen in his boat, they sit and talk. On the river behind them, you see a slow boat passing by, but from the camera-angle from the shot before up the river you can't see a boat at all.
Corrected entry: In the final firefight they are fighting a chemical fire with water. Water isn't used on chemical fires, as there's a chance it will make it worse, instead foam is used.
Corrected entry: At the end during the chemical warehouse fire, there is no color in the fire. The fire should have intense color in it, in particular the color blue in it, especially since it made the barrels shoot out.
Corrected entry: In the very first fire scene, where Brian's father is killed in a fluctuating backdraft, we see power lines extending from the apartment building as the truck pulls in at the scene. In this case, the truck is a ladder, which would have never been called into use under those circumstances unless the power was safely cut or turned off. In the very next scene the power lines are gone.
Corrected entry: During the final fire at the climax of the movie, there are several scenes from inside the building showing massive explosions and fire breaking into and through the warehouse windows from the outside. However, they also show several shots of the exterior of the building with explosions and fire bursting through the windows from the inside going out. So, which is it? Are the explosions originating outside the structure or inside? It can't be both, yet that is the way it is shown.
Corrected entry: In the end scene the dispatcher announces "This will be a hazardous materials response" but Brian and Steve and Axe have no masks.
Corrected entry: Both the engine and truck are first due at a downtown high-rise fire, yet their firehouse is in a quiet neighbourhood. Also, the final scene shows them responding first due to a fire from their firehouse, yet as the helicopter shot widens out, you can see the downtown skyline, nowhere near their firehouse.
Corrected entry: First thing I learned is that in case of a fire, one is NEVER to use an elevator. Yet, when the fire fighters enter that downtown building (the one where "Tim" is burned badly), they use an elevator. Even if the firemen were not sure whether the alarm was a real fire or just a joke by someone, they should take their task seriously and therefore use the stairs.
