Alien 3 is pretty much the procedural textbook for how studios interfering can ruin a movie.
They took one of the biggest IPs in cinema at that point, released a trailer before there was even a script - before any actors or directors had even signed on - and then hired-and-fired-and-hired-and-fired-and-hired-and-fired directors and writers like it was going out of style. And the script kept being re-written on the poor director (a rookie David Fincher) during production. Very little of his actual vision or voice made it into the finished product, to the point where he basically disavowed association with the movie and isn't very keen to talk about it. And that's to say nothing of the massively unpopular decision to kill off Hicks, Newt, and render Bishop down to essentially a cameo. Could have been a bold choice if they'd followed it up with a good movie - but they didn't.
Anyway.
The final trailer for Alien: Romulus looks deadly, but also commits the same cardinal sin all trailers fall victim to these days in that it shows way too much. I think out of 6 principal characters, we watch 3 of them die in the trailer? Kind of robs some of the suspense factor.
