During the last scene in Prometheus, how did the Engineer enter the ship after Dr.Shaw had locked the doors?
This question has been edited a bunch of times. I'll try and break it down:
Brute force I guess - he was also able to rip an android's head off. This may be something to come in a future director's cut, as I think a few minutes of fight scene were edited-out between the Engineer arriving at the pod and Shaw opening the inner door to the squid-thing (possibly to avoid an R/18 rating).
I'm also not sure that she actually locked the external doors, just closed the air-lock door.
Early on they state that the atmosphere is almost breathable, but with toxic levels of CO2. maybe the Engineer has a higher tolerance to CO2, or maybe he could hold his breath for the fairly short walk from the crashed ship to the life-pod.
Fifield (the geologist) brought the floating red balls in order to map the location - it sounds like they are standard kit for mapping caves or similar. Fifield refers to them has his 'pups'. They create the holographic map of the Engineer's pyramid on-board the Prometheus.
Not a clue. They have faster than light travel, almost-human androids and suspended animation. I figure they have some advanced space tech in there.
The map inside the Engineer's ship appears to be some kind of holographic orrery, though I don't think it maps to just one system or to scale. I'm not sure whether that includes some kind of Kinect-like gesture interface or whether David just appears to touch the map of the Earth.
