Covering the L.A. Times Hero Complex screenings and Q&A, Ain’t It Cool reported Ridley Scott’s revelations about the ALIEN prequels.
Yes, there are two movies planned, with both parts already scripted.
Scott told the audience his inspiration:
“…In the first Alien, when John Hurt climbed up and over the top of the rise… there was a massive giant lying in a chair. The chair was either a form of engine or some piece of technology and I always thought no one has ever asked who was the space jockey?”
Apparently, the film will be set long before the events of ALIEN, and we’ll discover that the space jockey seen in that film might have been a kind of space suit, rather than a decayed corpse. The audience will be shown who the ‘Jockey’ was, and where he came from.
“Terraforming” (re-making a planet into a preferred bio-sphere) will be a theme of the film, and there will be an attempt to depict space travel and this kind of project in a manner somewhat more realistic than most science fiction films.
