The Prometheus sequel is set for a 2014 or 2015 release.
The eagerly anticipated follow-up to the blockbuster is being actively pursued by studio Fox but co-writer Damon Lindelof may not be available to work on it due to scheduling conflicts.
Fox said: "Sir Ridley Scott and Fox are actively pushing ahead with a follow-up," and looking to a 2014 or 2015 release.
Scott has previously hinted at the name for the sequel which is expected to again feature Michael Fassbender and Noomi Rapace.
When discussing what he envisages in the second movie, he referenced the film's original working title, Paradise, suggesting it will be used next time.
He said: "From the very beginning, I was working from a premise that lent itself to a sequel.
"I really don't want to meet God in the first one. I want to leave it open to Shaw saying, 'I don't want to go back to where I came from. I want to go where they came from.'
"I'd love to explore where Dr Shaw goes next and what does she do when she gets there because if it is paradise, paradise can't be what you think it is."
The director views paradise in his movie as "sinister and ominous".
He added: "Because the Engineers are such aggressive f*****s. I always had it in there that the God-like creature that you will see actually is not so nice, and is certainly not God."
