Sounds good on the surface but the edit of the alien in the corridor doung that squat move is part of the Ripley trying to blow the alien out the airlock the first time and was an unfinished sequence…
The footage of the Alien squatting in the corridor (Box Alien?) is an outtake from this (later) sequence: Ripley heads towards the shuttle (after setting the self-destruct), bumping into the creature, she drops the container carrying Jones and rushes back to engineering, to stop the 10 mins countdown.
It’s not from the earlier deleted scene where Parker, Ripley & Lambert almost succeed in trapping the Alien in the air lock - which ends with Ripley’s nosebleed.
Nah it is but it intercuts with Lambert listening on the Intercom and Parker in the Corridor.
There is one shot in the trailer that proves that a part was filmed which has Ripley running through the smoke.
The Box Alien as you call it is just moved to the ending sequence instead of the failed attempt. You can see the airlock behind the box Alien.
This happens quite a lot of old films from the 70’s including Star Wars, moving shots about into other locations like R2-D2 on the death Star shots spliced ib when he is flying through Space on the millennium falcon.
It is easy enough to sort the chess game out then Later C3P0 tangled in the wires aboard the tantive cuts to R2D2 on the death star again laughing… If ypu were going to do a special edition that is a worthy cause for changing something or making it work.
Just thought a bit about the chess game on the DVD i think it is Empire of dreams the cut stop motion figures I wonder if they time exactly with the shots of R2-D2 on the death star? That would be a cool restoration… Although R2-D2 laughing would need an Adywan type fix…
