Greenland (2020)

Factual error: Smaller pieces of the comet start raining down in a highway setting. While small fragments of a comet can come down, they'd all be traveling at anywhere between 20 miles per second as the comet is an extra-solar comet. Those small pieces wouldn't make such piddling explosions, they'd be creating concussion waves that would rupture your organs and send vehicles flying. The heat even from those small rocks would ignite all foliage within 50-100 yards. (01:31:00 - 01:34:00)

Factual error: It would be virtually impossible to get from Atlanta, GA to Thule (Qaanaaq) Greenland in the time-span presented by the movie. The distance from Atlanta, GA to Ottawa, Ontario is approximately (direct) 1,200 miles which would take about 17 hours of driving, not counting breaks and side trips. The distance from Ottawa to Thule is approximately 2,200 miles. Plane type? Taking a guess, range of about 900 miles. Even with no fuel limitation, flying time approx 10 hours.

Factual error: The nuclear reactors on the US east coast, and European coasts, and their full fuel pools, would all have melted down and destroyed all habitable areas of the northern hemisphere, at the least.

Trivia: As the family is leaving home in their car, a neighbor asks that they also take her daughter, Ellie. ELE, pronounced the same as the name, stands for Extinction Level Event.

Nathan Garrity: My friend Teddy says your life flashes in front of your eyes when you die. I think it would be better if it did that while you lived. That way, you could see all the good memories and be happy.
