When Brian and Lori are freed from the tunnel, he joins her as she is already on a stretcher, which means he lingered behind in the tunnel after she was freed.

As a safety precaution, no one would be allowed to play with a ball on a plane, even a private jet.

When in the underground, there's no reason for Brian and Lori to use a flashlight, as the tunnel is well-lit.

The assistant mayor of a city would not have jurisdiction to redeploy fire companies, this would be done by the fire department heads.

Several of the photographs downloaded from the park victim's camera show him from behind while he is shooting those same photos. The shots are just stills taken from the original scene.

This is a Canadian film made in Vancouver but is set in the US. One sees many yellow NYC cabs, but in an early shot one sees a building at the front of which flies only a Canadian flag.

When Brian and Lori are freed from the tunnel, he announces that he is going to join his fire company. He then miraculously produces a firefighter's helmet.

Cassie announces to her co-workers that they are safe in the building, protected from St. Elmo's fire, but that they should warns others in the building. Shortly thereafter, others are seen evacuating the building. One floor in an office building would not be uniquely immune to the weather effects while others are not.

Contrary to the news reporter's question of "What is going on to our city?" because of global warning, it would be many cities and countries affected.

It is stated that Dr. Liggenhorn is the only civilian enjoined by NASA from putting objects into orbit. NASA has no law enforcement capability. Any such ruling would come from the Federal Aviation Administration.

Lori is referred to Cassie's sister and niece throughout the film.
