Didn’t Asimov have something to do with this? The original story or something?
Asimov did a novelization based on the screen play.
He also had science and continuity issues with the film:
Why didn’t the saline that was injected into Bennings with the Proteus grow in an hour and kill him?
The laser rifle, too?
When resupplying the Proteus with the air from Bennings’s lungs, it shouldn’t have worked because the oxygen atoms would have been too big for them to breathe in their shrunken size?
That’s just from memory.
