Corrected entry: In the scene where the female alien jumps through the glass wall of her cell, if you play it in slow motion you will see that the glass is already shattered a split second before she jumps through it. (As per MM's rules, if a mistake is significant the requirement of slow motion/pause to spot is permitted.)
Corrected entry: All the children that are born... where do they get their clothes so fast? They all must shop in the exact same place as well!
Corrected entry: At the end of the movie, when Natasha's character has been supposedly "killed", her carotid artery pulse is clearly visible on the side of her neck.
Corrected entry: In an early scene, it is claimed that Sil has a poison capsule in her that will release and kill her if she gets a certain distance away from the lab. Later she leaves the lab completely, but nothing is ever mentioned about the capsule and it does not release. Before she leaves she destroys some equipment, but it is apparently only the lockdown mechanism.
Corrected entry: In the scene where Natasha crashes through the glass wall of her cell, she is wearing underwear which is quite visible. Immediately after the chase scene, she finds the other alien, drops her dress, and is no longer wearing underwear.
