Factual error: Water can't put out chemical fires.
Suggested correction: Nonsense. Not all can be put out with water, some can.
If you did research on fires you will see that putting water on chemical fires makes it spread. Gasoline and oil float to the surface of the water and continue to burn.
Character mistake: In the part after the premonition when everyone runs out of the speedway, Cynthia Daniels yells "Andy" to her husband, when her husband's name is Carter.
Suggested correction: Cynthia isn't the one saying it. Nadia, Andy's girlfriend, is calling after Andy as she follows him out. If you listen closely she actually calls after him more than once, beginning before Carter even starts to follow them out.
Continuity mistake: During the pool sequence, we see a few shots of the pressure gauge, some close-up, some wider. In some some shots the scale goes up to 160, in others it only goes to 100.
Suggested correction: It's two totally different gauges in two different places.
Continuity mistake: During the last vision, Nick is seen driving in front of a bus however when the events take place the bus is nowhere to be seen.
Suggested correction: That is because, in his premonition, Nick spent time to look at George's body. After the premonition, he immediately drives to the Mall where Lorii and Janet are, wasting no time.
