* Americans say that Australia got a Typhoon. a) Americans call them Hurricanes b) Australians call them Cyclones. So why the heck do they use the asian name for them?
** "Typhoon" refers to Pacific hurricanes in general, including ones that hit the American Pacific Coast, so the average American would probably use that word to describe one hitting Australia. (This might not actually be the correct technical distinction between Typhoon/Hurricane, but it seems to be the general belief among East Coast Americans where I live)
** In the part of America where this troper lives, Typhoons are Hurricanes that are mostly water and Cyclone is a superhero. While not logical from a technical standpoint, in-character people calling it that makes sense.
* In the party scene at the school. Why the heck does Sam's name tag say 'Hello my name is Yoda'?
** Probably to show that his character has a sense of humor.
* Is it even possible for two twisters to join like that? Beside each other their sides would be going opposite ways. I would have thought that would have made them clash and cancel each other out. (Genuine question by the way.)
** Yes, it's possible, but not very common.
** Actually, two tornadoes in proximity to one another would spin around each other, often close enough to appear to be just one fat funnel, like a wedge tornado. In these cases, the stronger vortex will sometimes starve the weaker vortex of its energy source and kill the weaker vortex, or both will survive and get stronger.
* How the hell do they use a wood and paper fire to stop a wave of air so cold it makes ice crystallize on stone walls and freezes a human in seconds?
** In that same vein, as mentioned by Rifftrax: Why did the characters immediately default to burning the ''books'', especially when the preservation of First World knowledge and culture through books would probably be absolutely paramount in order to help humanity rebuild after having essentially the ''entire'' First World wiped out? Why not, y'know, the wooden furniture of the library, considering that wood burns warmer, longer, and leaves ''a lot'' less smoke instead of the remaining and durable repositories of knowledge and literature?
*** Paper burns more readily than wood, which is important if you're trying to keep the fire lit in spite of the extreme cold.
*** Which is an argument for using paper as ''kindling'', but not as ''fuel''.
* I find it odd from a film making perspective, that at $1 million a wolf, they went for using C.G.I wolves rather than real, trained wolves which would be better looking and cheaper.
** [[WordOfGod According to the DVD commentary, it was because]] [[NeverWorkWithChildrenOrAnimals they just wouldn't cooperate.]]
*** Must've been piss poor trainers. And besides, at 1 million a wolf, why wouldn't the CGI guys be able to make some decent wolves?
* Why are they huddling for days and days in a library when there's a perfectly good abandoned freighter floating down the street from them? Ships have things the library doesn't... such as diesel generators, climate control, long-range radios, food supplies, and beds. And yet nobody considers the freighter as anything other than a possible source of medical supplies.
** It'd been established that it was too cold to survive in even for a short period of time. Even if they were just travelling down the street, what are the odds they'd all make it. Plus they had a sick person with them, and they'd already set up a - rather weak - source of heat in the library.
*** Well, given that a later part of the plot has two guys surviving a round trip to the freighter and back without even taking a rest break, and being chased by wolves aside, I'd say the odds were somewhere around "one out of one".
* The part where our class full of honor students and science geniuses actually had the gall to act ''surprised'' that someone who'd gashed their leg while standing hip-deep in New York City sewer water might get an infected wound.
** Did she actually ''tell'' anybody she'd cut her leg?
*** Yes, given that she needed help bandaging it.
* Why did the global freeze stop at political frontiers?
** It didn't, even Jack said Texas would be fine. The entire population would probably think in terms of borders, so it would be better to tell everyone to make their way to Mexico instead of them all thinking "we're in the southern half of the country... we'll be fine."
*** Even so, the panning shot of the Earth at the end shows that Texas was completely covered in ice and snow, as well as Florida, both of which should have been spared. So no, they weren't fine.
* Just one question: [[BerserkButton ARE THE PEOPLE IN LA THAT STUPID TO]] [[TooDumbToLive DRIVE INTO A TORNADO THROWING CARS AT THEM?!]]
