Other mistake: When they raise the temperature of the room with the facehuggers in, once the room is at body temperature, they open the door onto the much colder corridor. This would have immediately dropped the temp in the facehuggers' room.

Directed by: Fede Alvarez
Starring: Archie Renaux, Cailee Spaeny, Isabela Merced
Continuity mistake: This film takes place after the events of "Alien." At the end of "Alien," the Nostromo is vaporized in a massive nuclear explosion, but in this film, massive chunks of it are found floating in space. Not to mention the fact that even if such giant pieces survived, they would have been propelled outward indefinitely and would not all be floating in the same confined area.
