Jon Spaihts' original script has leaked if anyone is interested. Now you can see how badly Lindelof ballsed it up

Thanks for posting that up.
Just finished reading it.
So much better, what a shame that wasn't the film.
Anyway, liked the early scene setting and the echoes of 2001 with the Weylands wheel.
p38 Much more realistic idea for the cameras rather than mysterious flying things.
p49 The Vickers David bit with protocol 2 established clarity of purpose.
p62 "Something different killed these" ....
p66 Customised bacteria
p69 The engineers aren't from here...
p71 The parasite.
p77 Oh yes, that's more like it.
p80 The juggernaut in a hanger.
p83 "David is off the reservation"...
p85 Proper Facehuggers!
p86 Oh yes. A white Goblin.
p90 Much more like a proper Alien film.
p91 Metamorphosis (the change from the chestburster to Alien finally explained)
p103 Fifield!
p104 A better end for Vickers instead of the getting run over nonsense we ended up with.
P110 An Ultramorph!
A much better ending too with the beacons.
Honestly, this would have explained so much (and that Prometheus was really a reference to David).
Why or why oh why.....this could have been so good. A tragic missed opportunity.
