It seems many mainstream media outlets have been sleeping softly under a rock for the past year, having forgotten that Alien 5 has been shelved until Alien: Covenant has had its run. The headlines today quoting franchise icon Sigourney Weaver's quotes concerning the Alien 5 project are becoming so rehashed it's borderline comical.
UK based media site Express have run a "new" story that has grabbed the attention of many top news aggregator platforms. In the report they call out Sigourney Weaver as "blaming" Ridley Scott for the postponement of Neill Blomkamp's Alien 5. This is not entirely true.
It’s one of those things we wanted to do this past year, but I think Ridley [Scott] didn’t want them all coming out at the same time.
For casual readers this may be shocking news, but to Alien fans and the members here at Alien5-Movie and Scified, we know this has been common knowledge for a year now and more so, is not something that needs to be worried about. Fox and Ridley Scott have decided to hold off on Blomkamp's Alien 5 until the Prometheus sequel is released. This makes sense as to avoid confusion between properties and to allow Ridley and Neill to formulate a coherent plot which can incorporate both ends of the Alien universe spectrum, intelligently.
What we ACTUALLY know for sure is that Fox took a serious interest in Blomkamp's Alien 5 script and had the project greenlight to begin prep. Concept artists were commissioned to create a number of pieces for the film prior to it being put on hold. Ridley Scott signed on as Executive Producer and is eager to see the project evolve and grow into something that can work, canonically with the rest of the franchise. We also know Alien 5 will NOT "erase" Alien 3 or Alien: Resurrection, as previously speculated. Alien 5 is happening, it's just not happening this year, and that's okay.
For those who wish to avoid the clickbait / rehashed news and who would prefer to remain up to date on actual "breaking news" on Neill Blomkamp's Alien project, then you've found the right place. Sigourney Weaver's comments have not changed for a year and they won't change until Alien: Covenant has run its course and Fox are ready to pursue Alien 5 to the fullest. With so much interest and profitability riding on this project, fans need not worry about its eventual fate - Alien 5 will happen. Just be patient.
