If they were going to do it, I think just take a page from the other horror movie reboots/resets. Make a new Alien that takes place after Alien 2, get Sigourney Weaver and Michael Biehn back as Ripley and Hicks, and recast Newt since the actress never did another film after Aliens. (Rosamund Pike is about the right age if I had my choice.)Saw a rumor today that Disney might be doing a major reboot of the Alien franchise.
Intrigued but wary. Trying to retell the first movie is a losing proposition, nothing can have that same punch. Ripley’s story has been told. There are others to tell. Tell one of those.
