Pandorum/Headscratchers

Why were Nadia and Manh fighting when they first meet? The real bad guys on the ship are pretty obviously not-human-looking.
- Everyone on board is suffering from Pandorum to a certain degree, thus everyone is more or less crazy. That is why Nadia attacks him on sight, she's a little crazy, though she calms down afterwards.
- Hunting is conducive to sticking together in groups. Scavenging is best done alone if your only defensive strategy is "run and hide." Unless you happened to be one of the hunting albinos, it was every man for himself; as we saw in the film, trusting another non-albino could potentially get you eaten.
- Because Nadia attacked Bower and Mahn had stepped in to help him.
Did they ever mention why Bower felt familiar with the corridor when he met one surviving crew member who was trapped and why Manh couldn't speak english?
- I gathered that he felt the corridor was familiar because, in a huge ship like that, the corridor layout is probably the same on adjacent levels, and he once again encountered a body-hanging-from-the-rafters trap, though it turns out to be a living crew survivor, rather than a rotting, disemboweled corpse, like the first time.
- Manh was probably recruited from a country that dosen't speak English. The ship was an international effort so they probably recruited from all over the world.
How did Nadia survive for months eating bugs?
- There was food seen around her hiding spot were she attacked Bower. It was a 123 year trip so there obviously must have been a massive food supply.
- Also, you can totally survive by eating bugs, and even keep quite healthy as long as you have large enough supply of the right kinds of bugs.
Why did highly educated people in a crisis situation lose language and become raving maniacs instead of just maintaining their civilization as most have done over the last few thousand years?
- Starvation is a great way to fall into cannibalism. They were locked in the lower levels by the guy with delusions of godhood, and left to fend for themselves. And don't forget EVERYONE on board the ship is suffering from Pandorum, everyone, making them paranoid and suffering from hallucinations, including the people who were locked in the hold and eventually became the ancestors of the albinos.
- Actually, the passengers caught Pandorum and Gallo convinced them to take part in cannibalism. Leland said he left them there to fend for themselves AND feed on their own. They were called "those who had behave" meaning those who did as he desired. He attempts this with Bower at the end of the film, telling him that "life eats life" when he starts suffing from Pandorum. Also, Gallo never thought of himself as a God but a king.
