Just read this. Hummmmm, sounds like he's covering all the basis (and his backside) with this. Now one of them will be THE direct prequel to Alien and the other as previously reffered to as "Paradise" the brand new storyline.
"While excited about his collaboration with director Ridley Scott who makes his triumphant return to both sci-fi and the world of Alien, Damon Lindelof doesn’t want to count his xenomorphs before they’re hatched. The writer, who worked closely with Scott on the script, wanted to make sure that the story presented in Prometheus answers enough of the questions brought up in the new film while also leaving the possibility for a sequel.
“Ridley was very interested in talking about, ‘What are the answers to the questions that Prometheus is posing that are not necessarily definitively spelled out in the body of Prometheus?’” the Lost co-creator told The Hollywood Reporter. “I said to him, we should be prepared for people to feel frustrated if we’re going to be withholding, so we have to be very careful about what we’re saving for later,” he continues. “Because it’s not a foregone conclusion that there are going to be sequels, and so if there isn’t a sequel, just be comfortable with what we gave them in this movie.”
Lindelof pointed out that the film will serve as the father of two sequels; one of them is obviously the already-existing Alien, but the other, at one point referred to as Paradise, would flow more directly from this film. “The audience is given a little more information than the characters in the movie have,” he said. “And it’s our hope that fires the imagination up enough for them to say, ‘I might want to see Prometheus again’ or ‘I definitely want to see where this movie takes me.’ Because this movie has two children: One of these children grows up to be Alien, but the other child is going to grow up, and God knows what happens to them. And that’s what the sequel to Prometheus would be.”
Prometheus, which stars Idris Elba, Charlize Theron, Michael Fassbender, Noomi Rapace and Guy Pearce, opens Friday.
Personally I don't think he has a clue what he is on about and hope he goes back to TV double quick.
