Errores

In the briefing scene with the President, Jack dramatically draws an evacuation line across the map of the United States. The line has been clearly redrawn. For the closeup shots over Jack's shoulder.

When Jack jumps across the gap at the beginning, all he his holding is the sample tubes. When he falls, however, he suddenly has an ice pick.

When the cleaner looks under the door, the very bright light shining from under the bottom of the door lights up the wall behind him casting a strong silhouette shadow of him on the wall, But it doesn't light him up as bright. Then the shadow raises its arms before the cleaner does, revealing its not his real shadow.

When one of the British scientists is asked where the "malfunctioning" buoy is, he first has to push a few buttons to answer the question. But at the very beginning of the scene, you can see it says it right on the screen: "Georges Bank".

When Jack and his team are trekking through Pennsylvania, Frank falls through a glass skylight roof covering a mall. When Jack looks down at Frank, he is lying over the hole looking down, and the glass is supporting Jack with a iron support beam. In the next shot, the beam is missing.

It's stated that the temperature that froze the gas lines was -150 degrees F, but when the pilot opens the door, you can see his breath. At 90 degrees F below zero, your breath will freeze and fall to the ground.

When Jack and Dash reach the library where Sam is taking refuge, they initially can't find it. When they do discover Sam inside, the fireplace is clearly lit. That means that smoke should have been visible from the outside. If the chimney was covered by snow, then smoke would have filled the room where the survivors are, yet there is none.

The penicillin aboard ship was found in solution. If in solution, it should have been found frozen, and it is clearly liquid when picked up. Normally penicillin is stored as a powder and reconstituted (by adding water or sterile sodium chloride solution) just prior to use. Penicillin in solution is not clear; it is a milky white color.

Several times during the film, including the British helicopter crash and the penicillin retrieval from the cargo ship, characters are seen touching frozen metal with bare hands, yet their hands do not stick.

Hailstones are shown as plain clear chunks of ice. Because of the way that they form, hailstones are opaque balls of concentric layers of accumulated ice (like rings of a tree), or agglomerated lumps of smaller stones.

After the reporter is hit by the flying billboard from the tornado, the billboard flips over and there isn't a body. In the special features on the DVD, an animatic is shown, showing the reporter was left on the road, as opposed to him being stuck on the billboard.

When a big storm threatens land, hurricane centers do not send helicopters out into storms so they can investigate them. During a storm, helicopters only rescue people and help bring in storm supplies to the affected areas. In the movie, three British helicopters are flying towards a massive storm over Europe to research and investigate it. Helicopters never fly into storms that big and strong because they weren't designed for that type of weather. They should have instead used Hurricane Hunter airplanes to investigate the storm.

But the dialogue clearly states that the three helicopters are not there to research and investigate the storm. They are flying to Balmoral, the British Royal Family's Scottish residence, on a mission to rescue Her Majesty the Queen.

The wolves break free and run away from the zoo before Manhattan floods with very high water and freezes over. After it happens, the wolves appear alive and running amok. It's possible that they went into a building (there are a vast number of buildings in NYC) to a high floor and stayed there until after the streets of Manhattan flooded and froze over.

Jack says he's walked from NOAA to NYC in the snow before. NOAA is in Silver Spring, MD. The NYC Public Library is on 5th Street in Manhattan. That's a 220-mile walk. In the best of conditions, it would take close to a week to walk there (factoring in rest stops, 8 hours of sleep per night, and the fact that in the movie, you'd be walking across the frozen Hudson River instead of taking the ferry). ~ CORRECTION: They were able to drive most of that distance before the roads became impassable. They only had to walk from "just north of Philadelphia", roughly 75 miles, not 220. Still quite a challenge in a blizzard, but they were used to doing research in similar conditions (like Antarctica).

At the end of the movie, the President mentions that they are taking refuge in a foreign country. It is assumed that it is because ice covers the US. When the camera pans back on the planet to show the ice cover, it clearly shows the state of Florida is almost all green, suggesting it is still habitable. The President could have set up government from there. ~ CORRECTION: During the briefing of the President (at around 1 hour 3 minutes), Jack does suggest evacuating to Texas or parts of Florida that aren't flooded. However, because so many people need to be evacuated, he explains that "Mexico would be best."

All throughout the movie, there is no condensation coming out of people's mouths when they are in a cold environment (with the brief exception of the helicopter pilot exiting the crashed chopper moments before he freezes to death).

When Jack and his team are traveling through Pennsylvania, Frank falls through a glass skylight roof covering a mall. Jack swings his metal pick axe into the snow to stop everyone from sliding though the hole and hold the weight of the three men, one of whom is dangling in midair. A moment later Jack, still in the same spot, wipes of a few inches of powdered snow to reveal they are all on top of the glass roof of a mall. Thus, when Jack used the pick, it should have gone through the snow and broken the glass roof he was laying on.

Onboard the ship, the pharmacy is locked from the inside, with a type of key in the door, which means it could not have been locked from the outside.

When the students are flying through the thunderstorm, you can hear typical rolling thunder. However, rolling thunder is an echo caused by surrounding storm cells. It would not be audible at the height of a plane flying.

When Lucy checks up on Peter, he's hooked up to some life-support machines. When the hospital is being evacuated to the south, Lucy agrees that she will stay behind with him till the ambulance arrives. The power is left on. As the ambulance finally arrives all the power is turned off. Since the heater is off, they both would have died from hypothermia. Peter would have also died without power to the machines that keep him alive. There should have been a backup generator to keep both the machines and the heater on.

In the shot establishing the upset animals in the zoo, the bear cage shot is clearly flipped, as seen by the word "BEAR" being backwards on screen.

When Jack's group is shown in Pennsylvania and Frank falls through a skylight, he is shown being suspended roughly 40-60 feet above the floor below. That means that the snow would be covering the entire mall and thus have drifted to a height of 65-70 feet at minimum. Given that only hours and not days had passed, this would be impossible, as that much snow falling in such a short period would have collapsed the roof well before the group arrived.

When Jack arrives at the spot where the library is, it appears barren. But when he goes inside the fire is blazing, which means smoke should be visible from the outside.

When the homeless man is ripping pages out of books to put them under his clothes to keep warm, he explains "Newspaper's best, but this'll do". There are many newspapers in the New York Public Library, as there usually are in any bigger library.

When Jack is walking to rescue Sam and Frank falls through the roof of the shopping center, Jack stabs his pick axe into the snow. As can be seen everywhere, there's no ice there, but only a thin dusting of snow, so he'd get no purchase with his axe.

After the Global Warming Conference when Prof. Rapson is hailing the cab, he removes his fingers from his mouth before the whistle is finished. That type of whistle requires fingers to remain in the mouth.

When the cleaner is walking towards the brightly lit door, you can see the shadow of the boom operator behind him.

The cameraman's reflection can be seen in the right-hand side of the Porsche during the tornado sequence.

The view shown from the ISS of the earth covers a far larger area than what can actually be seen from it, as the ISS is in a very low orbit.

There is no way a cargo ship could fit down 5th Avenue by the Library. The buildings there don't have enough space between them to allow it through.

When the tsunami hits Manhattan, there is no sign of Brooklyn in the representation of New York harbor. In reality, the tsunami would be unlikely to reach Manhattan without striking Long Island first. Also, the shot of water flooding the avenues means the water turned 90 degrees after it first hit Manhattan.

It doesn't make sense for the group leaving the library to make their way to Staten Island via Brooklyn. (They could have just crossed the frozen harbor, for example).

During the "Sky TV" report about snow in the British Isles, the cars are on the right hand side of the road, and a yellow American style crossing signal is seen.

The Russian cargo ship that drifts into the street outside the library, appears to be completely undamaged and seaworthy. So why are there no crew on board? There is no obvious reason for them to have abandoned ship.

When the group is taking refuge in the library, they choose to burn books to keep warm. Not only are books rather hard to burn without an accelerant, the group has a huge supply of wooden furniture and doors that would make much better fuel.

When one of the people who left the library considers turning back, the other guy says "Half the city is frozen and underwater. There's nothing to go back to." Half a city is not nothing. Half a city is half a city. There are still plenty of buildings in New York City to take shelter in.

In the final scenes, when helicopters rescue survivors in NY, people congregate on the roofs of skyscrapers. How did they manage to get onto the roof from inside the building, when the roof is covered in more than 10 feet of snow and ice?

When storms that move in a circular motion increase in size, their wind speeds tend to increase as well. Throughout the whole movie, the wind speeds don't quite match up with the continent-sized storms. They don't move as fast or as hard. They only blow just a little bit. Storms of that size and magnitude would have produced extremely dangerous winds speeds and gusts well over 175 MPH. The snow and ice wouldn't have been as deep and thick. Everything on land--including the skyscrapers in New York--would have been completely destroyed.

American glaciologists in Antarctica are heard using US units of measurement during their work. The metric system is in use by glaciologists - even American ones - in all scientific contexts.

During a meeting with his cabinet, the President stands and leaves, yet everyone at the table remains seated. White House protocol requires that when the President stands up, so does everyone else.

Jack is looking at a satellite photo of a large storm over Scotland and mentions it looks like a hurricane. The female scientist then adds: "Except hurricanes don't form over land." Scotland is a narrow point of land on an island. With a storm of that size, the United Kingdom's islands would not nearly be enough land mass to stop it from forming.

In a scene where a reporter is speaking of people going to Mexico to escape the storm, she says that people are fleeing "in the wake of the advancing storm". But "in the wake of" means following something, not preceding it.

In the shot where Jack Hall is explaining why the air coming out of the cyclone is so cold, the computer model of the low pressure system is spinning clockwise, not counterclockwise, as it should be in the northern hemisphere. Also, in the starlit picture when the weatherman says that the low pressure systems resembles a "tropical hurricane," it's also spinning clockwise.
