The aliens don't have Gold Fever just because it's shiny.Dolarhyde is bewildered by the aliens wanting gold; "What are they gonna buy?" Answer: gold is an essential component of their gravity tech(and any weapon that Blows Enemies Across The Room violates the conservation of momentum, so their weapons are also gravitic). When they abduct Lonergan's girl, the gold coins on the table melt and fly into the air. Their method of mining for gold involves gizmos that do just that, but why would they be using said gizmos on a little house on the prairie? Any gold within range of the gravity effect will melt and float, similar to magnets magnetizing ferrous materials in contact with them.
Ella is a Ascended AncientShe takes human form to save humanity from the aliens, which are probably at least partially their fault. Either they really did destroy the Ancients (unlikely) or she's lying. She may actually still be Ascended, judging by her regeneration. Nobody ever believes the cowboys' story, and the existence of aliens stays secret for over a hundred years. Also Reapers.* If she was an ascended ancient, she could have blown up the ship without descending extremely easily. The penalty for her would have been exactly the same.
The aliens will invade again ~100 years laterAnd go up against nukes and missiles.
Ella doesn't die at the endShe took on a different more transportable form and left Earth to save other planets. There's presumably still more of them invading other planets, as Ella says the ones on Earth will come back with reinforcements later.
Ella is a Time LordCome on! She regenerated, for cripes sake!
The mining town is actually Roswell, New Mexico.Aliens. Need I say more? New Mexico is out west, and it's deser-ty enough...
The Aliens stole the ship and acompanying techThey're basically space cockroaches with a modicum of intelligence; enough to fly the ship and fighters, and use some of the tech, but they don't really know how it works or how to modify or repair it. This is why they had to mine on a habitable planet: they can't build or operate an asteroid mining facility, and they're too stupid to think of it anyway.
The Aliens are ancestors of the PsychlosThey share the same lust for gold and crippling stupidity that allows humans to defeat them. Between the time of this movie and the time of Battlefield Earth, they evolved from reptilian creatures to those idiots.
The kiss Ella plants on Jake was magical/telepathic like the one Superman used on Lois Lane.She kisses him, the weapon falls off. Obvious.
The events of this film are an alternate timeline - reverse engineering the remains of the ship sets off the Steam Punk revolution.
Ella is QuorraThe whole movie takes place in a mostly isolated part of The Grid, where the graphics are styled like Westworld, rather than in shiny-black-and-neon. Quorra was sent to save the townsfolk, bandits and indians (who are all programs) from the aliens (a virus whose weapons are hacks) who are stealing the molten gold (data streams). Ella|Quorra doesn't die and resurrect; she is de-rezzed and rebooted.
The aliens are mercenaries.One biologist to examine the natives on the target planet and a bunch of not particularily bright brutes who are supposed to fly, push buttons and dispose of possible... irregulations. The ones who actually know how all their tech works aren't present (except for one or two for maintenance) and the heads of the whole project might even be of a completely different species.
