Other mistake: Ambrose smacks a stone on Ethan's forehead. No blood nor even a bruise appears seconds later when Ethan is kicked in the face and we get a close-up of him.
Other mistake: Luther tells Ethan that he will only have 40 seconds for the louvres to remain open for him enter the ventilation shaft at Biocyte before the alarm goes off. But the warning message on Luther's computer says that the limit is 20 seconds. (01:06:30 - 01:09:10)
Continuity mistake: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tyres to road slicks, back and forth depending on what terrain they were on. Easiest to see when Ethan skids on the road to avoid the white van - clear shot of slick tyres - then about 30 seconds later they're on the dirt, he skids into the old car and you can easily see that he's got off-road tyres front and back.
Sean Ambrose: In just a few hours you can be assured of going down in history as the typhoid Mary of "Aus." G'day.
Trivia: When Nyah is trying to convince Ethan to shoot her, she says "Do it. Now!" There is still about forty minutes left in the movie, but those are the last words she says.
Question: Why didn't Ethan just give Nyah one of his guns after she infected herself? She could have easily killed Ambrose and others with a surprise attack since they were more interested in keeping her alive and she wanted Ethan to kill her anyway. She had better odds of surviving that way than the impossible plot that followed. She could have killed everyone but Ambrose and he may have let it happen in order to still have a chance at selling the virus.
Answer: Ethan did not want her to kill herself. Giving her a gun would allow her to do so.
