They won't do it. But I do believe Ridley would have if he did get to actually make his
Covenant sequel a few years ago.
Would have been very curious to see how it was pulled off, that's for sure. Plus, regardless,
Alien will always be there as it was conceived back in '79. Even as much as I love
Covenant (and am interested in
Prometheus' ideas), it isn't like the prequels really enter my mind or skew my perception while watching
Alien. They're different films.
