We’ve been waiting to hear some update concerning the Alien franchise and while there has been some teases from Ridley Scott that his third prequel Alien: Awakening is still in development phases. A fifth Alien film starring Sigourney Weaver as Ellen Ripley might be still in the cards despite the Neill Blomkamp incarnation of the project being placed on ice.

While speaking with Empire, Weaver revealed that she received a 50-page Alien 5 treatment 18 months ago from franchise producer and screenwriter Walter Hill. Hill has been part of the franchise since the original 1979 film and worked on scripts (including rewrites and treatments) for Alien, Aliens, and Alien 3.
She doesn’t sound as enthusiastic about Ripley’s return it as she was when Blomkamp was attached for Alien 5 as it sounds like Ridley Scott could be calling the shots.
WEAVER: “I don’t know. Ridley has gone in a different direction. Maybe Ripley has done her bit. She deserves a rest.”
I think Alien 5 is still the best way to go. Neill Blomkamp wanted to make a film that directly connected to Aliens with the return of characters such as Newt, Hicks, and Bishop after being killed-off in Alien 3, which was co-written by Walter Hill.
There is a good chance that Hill’s version might have been a continuation from Alien: Resurrection following a clone version of Ripley. Something that had been the original intention of Alien 5 when Ridley Scott and James Cameron teamed-up for their own incarnation before the studio passed to make Alien vs Predator instead.
At one point, James Cameron was able to read Neill’s script and called it “gangbusters” during an Aliens Anniversary panel at San Diego Comic-Con back in 2016.
Ridley Scott has seemingly been the main reason Alien 5 hasn’t come together as he pulled his weight at Fox to have Alien: Covenant made instead of Blomkamp’s film, essentially killing it in the process.
