Is he referring to the alien itself wen he says about 'its been used up'? I hope not, because I was under the impression this was actually going to be an Alien film this time around.
I have some kind of confirmation by someone very close to the production... Ridley thinks that the idea of Alien running around and killing the crew of the ship is used up... so thats what he thought when he said that.
.. He now wants to explore the origin of the creature (thats 100% confirmed and we know that), and its purpose. From what I know and I would never lie that I have some great infos about the story, Ridley will introduce someone/something new
in this one (and that creature will play some kind of role in the future movies), and the ultimate story of Xeno will be intertwined with the stories of human creation, Engineers and Davids story also!
This is not too much but at least we know that Ridley isnt going to make a movie about Alien chasing humans and killing all except last human survivor... Someone I know asked Wayne Haag about the number of the cast via private mail but he wont reply
One more thing we can speculate from what Ridley said is that
David is going to have some major part in the whole story... Everything else is not so certan...
From video Stolen posted:
Now we go to the next one, the next one is who made it (Xeno) and why, and I'm not
going to tell you, and why will be explained
From that we can speculate that te ultimate creator of Xeno is someone new...
Engineers in that case did not created Xeno and black goo! So here we come to the murals with Engineer and the kneeling (sleeping) creature with the beak. To me that mural represent the act of Engineers sneaking and stealing something from that creature (maybe black goo which is in fact the blood of that creature)... Next mural shows that same creature holding the well known egg... So we can make a presumtion that creature with the beak (kneeling creature) created egg to punish Engineers, or something like that... Of course all this are my presumptions but something like that could be true... If we analyse deacon mural we can see that the Xeno-like creature (Deacon) is in fact chained... so we can make more presumptions from that, but its best to wait the movie and see!
So Ridley wants to lift entire Xenomorph story to greater dimension. He began that process with Prometheus, but was a bit hesitant to answer question about Xeno and its origins. Now he wants to answers some questions, but I myself think that he is going to end the third movie with a major mystery and that would be something about crashed juggernaut and Ripley...
They wanted to "distance" from original Alien story but not from Alien itself!
So, no more cat and mouse story in a traditional way. This is 100% confirmed info!
We shall see all the horror, but there is now a bigger story revolving! And those stories are: Xeno and its purpose, human creation
, motif of god and of life and death, exploration of David's character (maybe he would become major antagonist or even ultimate protagonist and we know that androids are Ridley's constant obsession! Remember David's sentance about parents and scene with hologram in which he holds holographic Earth!), they will explore why Engineers wanted to destroy something they created...maybe humans are ultimate threat...
