) What ends up killing the parasite that was attached to the guy's face? I believe they said that it died on its own, but then why was it crawling around on the ceiling....just dumb luck that Ripley was walking underneath it, when it keeled?
As I remember, the face huggers live long enough to deliver the egg (that eventually bursts from your chest) into their victims, then die.
2) At the end, when Ripley blows the hatch in the escape ship to have the alien sucked out in to space, what re-seals the hull? At the beginning of Aliens, a resuce team is shown cutting through the hull to get at Ripley.
Doesn't she re-seal the airlock? I'm not sure about this one.
Great movie, especially since they couldn't show the alien much (special effects issues).
