Pandorum/Fridge

Fridge Logic - Apparently, the mutants were the result of genetic manipulation which would allow the people to adapt to living on Tanis, but instead was wasted on adapting to scavenging on a spaceship. Does this mean that the survivors now might mutate themselves to live on Tanis? While they probably won't end up as cannibalistic albinos...
- However, it was revealed that they had been aboard the ship for 923 years, and at least 900 of those years were after Gallo had gone Ax Crazy - which means almost a millenia of evolution/psychosis and breeding had occurred - just think the Reavers, and that's about what you have for those on the ship.
- They are not mutants since mutants are the result of a instance of mutation and this change happened over generations. Plus they didn't evolved into cannibals their ancestors became cannibals due to Pandorum and Gallo's influence. They adapted to hunting/fighting each other.
A single hull breach (albeit a large one) causes all the cryotubes to eject. Shouldn't there be some sort of blast door that seals off the affected area instead? Come to think of it, why did the Elysium have a cryotube eject system at all after the first Pandorum incident? Ejecting in deep space would be suicide; even if Earth WAS still around, rescuing the colonists in time would be impossible.
- Simple: It had a cryotube eject system in case The ship crash landed on Tanis]], right? The real question is, Why wasn't the space ship capable of detecting that they were on Tanis in the first place, unless a hull breach occurred??
  - The ship may have detected it was under water and was waiting for someone from the flight crew to make the call - and we know how well the flight crew was doing...
- Actually, the ending proves that the cryotubes ejection system is useful outside of deep space. Plus, the ejection of the cryotubes would make sense in this case, as the flight deck was destroyed. And it most probably did detect that they were on Tanis, because it did land itself. All of the systems are based on the assumption of an operating flight crew, thus they would wake everyone up.
Fridge Logic - How could an Earthshattering Kaboom wipe out all of humanity if there were ships and colonies throughout the solar system? It would be more believable if some superweapon caused a supernova or some other Class X-2 event.
- Where was it stated that that ships and colonies throughout the solar system at the time?
  - There certainly were other deep space missions, the Eden flight was one after all. But there's no mention of other self-sufficient colonies. Tanis is described as unique. Hence, it's possible that the final message that reached Elysium came from one of these ships, where people could survive potentially for months or years, but would be doomed because there was nowhere to return.
Fridge Brilliance:
- Surely over the course of several hundred years something would have happened outside of the ship to clue the people inside that they had landed - a minor earthquake, a wayward ocean current moving the ship, or if they had landed at a slight angle things wouldn't fall straight downwards etc - but obviously the artificial gravity is still operational, dampening the effects that happen to the outside of the ship to the inhabitants inside.
  - Actually, that would more likely be Fridge Logic - artificial gravity systems would require some source of power. Most of the film, however, revolves around Bower trying to reach the reactor specifically to restart it and restore power.
- The windows were probably covered like the window in the control room.
Why did the cannibals mutate as they did? Once woken a person doesn't ingest any more accelerants. (If you pay attention there's a warning sticker on the cryo capsule not to ingest any more of the paste) ...then it occurred to me. What di the canibals eat? The hybernating crew... chock full of said accelerants, so they've ingested ever more of the stuff with each and every meal
- The accelerants had stayed in their systems to make evolution happened alot faster.
Fridge Logic: How does anyone know what happened on board the Eden? There were no survivors, after all, and the ship's log most likely would not have had the level of detail discussed by characters on the Elysium.
- It doesn't really say that were no survivors.
- Even ordinary airplanes have black boxes that record everything that happens in the cockpit. Why on earth would a spaceship with the crew of 5000 lack this simple feature?
The power is down, so there is no artificial gravity. So how come the floors are all down and the ceilings all up, especially if they've crashlanded and are at the bottom of the ocean?
A bit of Fridge Brilliance: throughout the film, there is shown to be some kind of algea growing on the walls of the ship, foreshadowing that the ship was actually submerged.
