When the second shuttle launch is shown, one piece of footage shows the main engines building up thrust and the the shuttle starts to take off. The next shot shows the engines firing whilst the shuttle is still on the pad.
During the second shuttle launch sequence, the Solid Rocket Boosters are seen being jettisoned, but the next shot shows them still attached.
In the sixth minute the windows of the SUV driven by Kelvin are clear, but after they are fired upon by the pursuing vehicle his SUV's windows are tinted. Then, they are again clear glass.
In the seventh minute the pursuing SUV can be seen pulling even with the SUV Kelvin is driving, then from his perspective the pursuing vehicle again pulls even with his.
In the 25th minute one sees the launch time on the monitor as under a minute, yet about 30 seconds later the launch command as given as "3, 2, 1, go."
Near the start of the film, a decision is made to speed up the countdown of a space shuttle, apparently to get it off the pad before it might be hit by meteoric debris. There are thousands of actions that have to be performed during a shuttle countdown, and most of them simply can't be skipped. It is certainly impossible to simply jump to the final 5 seconds of the count.
The countdown reaches zero, the shuttle's main engines start up, reach full thrust a few seconds later, and then the Solid Rocket Boosters ignite and the vehicle takes off. In reality, the shuttle's main engines are started up a few seconds before lift-off, so that the shuttle launches at the zero point in the countdown.
In the beginning of the movie when the bad guys are chasing Kelvin and his family, they jump into a semi-truck to get away and he turns the key and the engine starts right up. A semi-truck like that has a diesel engine with glow plugs. You have to turn on the ignition and wait while a warning alarm beeps, then when the alarm stops, you can turn the key and the engine starts.
It is reported that the Spitzer Space telescope had detected bursts of gamma radiation. In fact, Spitzer is an infra-red telescope, measuring electromagnetic radiation which has a longer wavelength than that of visible light. By contrast, the wavelength of gamma radiation is shorter than that of visible light and is about 1,000,000 times shorter than that detectable by the instruments on Spitzer.
It is reported that the bursts of gamma radiation are a prelude to a supernova. Although the gamma rays produced by a nearby supernova could have catastrophic results for Earth, gamma radiation is not a product of the build-up to a supernova explosion.
Despite the title, this movie has no connection whatsoever with 2012.
In the sixth minute of the movie in the car, Laura addresses the driver, Kelvin, and asks "Ryan, can you slow down?" It is possible she mistakenly addressed the character of Kelvin by the actor's real name, Brian Krause, but even that she got wrong.
In the 18th minute Laura is looking for Tina's mom's necklace while an agent awaits to escort them to the base. But Laura is looking in kitchen drawer and cabinets.
There are frequent CG-generated flames, fires and effects which are clearly unreal.
When Kelvin and his family try to flee the assassins in the semi-trailer, the assassins shoot at them with submachine guns but in several instances, there is no sound while they are actually shooting and sounds when they aren't.
In the fifteenth minute, Dzerzhinsky speaks but his mouth does not move.
In the 26th minute when Dr. Kwang addresses Ryan Kelvin, on the instrument panel behind them there is a light and what appears to be a crew member reflected.
We are told that Kelvin made 4 spaceflights in the past year to take nuclear weapons up to the space platform. This is supposedly in preparation for saving the Earth from the effects of a supernova, but it isn't possible to have that much warning of such an event. We actually learn of a supernova by observing it after its initial explosion has taken place - we don't find out about it in advance.
The people chasing Kelvin appear to be trying to kill him, shooting at his moving vehicle with automatic weapons. Yet when they catch up with him they start asking him questions about his activities. He could not have possibly given them any information if they had managed to kill him.
Four people go out to the shuttle launch pad to inspect it, They drive in golf carts, which means the 7-mile round trip would take a minimum of 30 minutes for one of the top-speed vehicles. Driving a normal car at 70mph (bearing in mind this is an emergency) they would be able to cover the same distance in 6 minutes.
The Public Affairs Officer announcing the countdown calls out; "5-4-3-2-1-Zero. Go." No countdown ever ends this way. "Liftoff" would be more appropriate than "Go".
Despite Kelvin's daughter advising her mother to stay away from the trees when they are trying to escape the lightning, they both run very close to trees several times.
