When Ash says 'Kane's son...'

I'll pitch in on this one since I've seen Alien about six and a half thousand times now :-P It's definitely "Kane's son."

@cypher really 6500 times?

Just about that ;-) It's well over 100 at least :-P

i dont know if its already been mentioned but to me, Ash reminds me a lot of the concept of HAL9000 in 2001/2010 - where its sort of explained that HAL goes crazy and kills people because it was "lied to" or given conflicting/illogical orders - its developing AI couldnt handle the situation so it went crazy. im not sure if im explaining this the best way but if you are familiar with those films, to me this kind of makes sense in Ash- as though he goes a little haywire as a result of his mission and his own AI. it seems to me that in the Alien films the andriods arent merely logical computers but slightly more like Data from Star Trek - that perhaps they can develope personalities of their own and even perhaps "feelings." it sounds like this will be explored more by David in Prometheus. and even though Aliens is not my favorite of the films, its pretty good in its own right - and i loved Lance Henriksen's andriod. "i may be synthetic, but im not stupid." or in Alien 3 something like "i could be repaired but ill never be top of the line again, id rather be nothing." i think Ash is like this as well... but not as developed in that sense. just a potential way of seeing these things. of course i fully agree that Ian Holm's performance is excellent. really every member of the Alien cast brought a lot of "magic" to the film.

@jenskarlsson, The illogical orders/lied to scenario was a later addition by Arthur C Clarke in 2010: Odyssey Two as the reason for HAL's insanity. Although, it is clear that in 2001 HAL was programmed Not to inform Dave and Frank about the true nature of the mission, it is never implied that that programming was the specific reason behind HAL's murder spree, though it might have added to his stress. As an aside, in 2001 Heywood Floyd clearly is "in on it" but in 2010 he was ignorant/innocent of this deception. Continuity issues aside, it is a good explanation, though. I just like HAL going crazy with no real explanation. A bit more frightening. Which is the way Kubrick wanted it, as he envisioned HAL as being more human than either Dave or Frank. But Clarke was always more of an optimist than Kubrick and wanted to save HAL. I do think it is a fair comparison when looking at the script for Alien: Ash was not programmed to hurt any of the crew, much less murder them. He even states that the Company hoped they could contain the alien. The finished film contradicts this by stressing that the crew's lives were "secondary" thus giving Ash at least indirect orders to kill if necessary. In this case, Ash would not be going haywire, but acting perfectly as programmed. It is one of the few changes from script to screen I am not a fan of. In another thread I think I called Ash a nightmare version of Data.

I finally noticed on my own that line while watching Alien for the millionth time. Another line that was hard to notice was Parker's last words: "Get out of the room!"
