Finished with 'the carpenter that got away from me': Dark Star (1974)
The fuck did I just watch? With that 'alien' early on I was not expecting a comedy of sorts.
Also, lots of stuff got transferred into Alien, particularly the computer bits. Does explain why the original screenplay has a voice for Mu-Th-Ur as well. Thankfully that got removed in the process towards the movie we now know, even if O'Bannon was pretty heartbroken about all the changes.
It is fun to notice how they actually filmed the 'space' and elevator scenes though. And despite being a comedy, there is evident writing skill, even if most of the techtalk is sheer bullshit. (this happens in Alien as well, when they 'turn on artificial gravity' while they're taking off from LV-426. Like, you wouldn't need that at that moment). I will say that he almost got the age of the universe right, if the actor hadn't said '13,2 trillion years' instead of 'billion', which it is in real life (13,8 billion standardized Earth years, to be precise). But obviously planets going out of orbit and being absorbed into their host star does not cause a supernova, nor is removing them without consequence to other planets (I won't bother you with details).
Fun use of concepts though.
edit: oh, this was their student film. Huh.
