Ridley Scott recently commented about the Prometheus franchise, saying that he plans on keeping strict control over its direction.  In an interview, the actor stated, "I'm trying to keep this for myself. I let the other one [Alien] get away from me - I shouldn't have."

Scott directed the original Alien film, but then the franchise was passed along to other directors, such as James Cameron and David Finch.  

"I'm trying to re-resurrect the beast and let if off the hook for a while because I'm coming back into the back-end of Alien 1. I'm gradually getting to Alien 1."  He went on to say, "Prometheus 2 will start getting shot in February and I've already begun now so I know what the script is.Then there will be another one after that and then maybe we'll back into Alien 1, as to why? Who would make such a dreadful thing?"

Prometheus was released in 2012, and its follow up is slated for a 2017 release.
