Corrected entry: When Ambrose is impersonating Ethan on the plane ride, he not only speaks in Ethan's voice with the voice changer but also Ethan's American accent. But when he removes the voice changer his accent goes back to Scots. Wouldn't he still have his Scots accent even with Ethan's voice? (00:05:05)
Corrected entry: When Nyah tries to flee from Sean's house she runs into Sean disguised as Ethan. This is highly unlikely for two reasons: 1. Sean only knows that Nyah tried to con him, but he does not know Ethan is involved. 2. Even if for some reason Sean would have discovered that Ethan is involved, it is impossible for him to have a mask custom made (and to know the sound of Ethan's voice) on such short notice.
Corrected entry: In the scene where Ethan is fleeing from the old car and the Range Rover, both vehicles are able to keep pace with his "crotch rocket". Any bike of that size could out pace those vehicles by miles. There is no way that the trucks in the big chase scene would have kept up with Tom Cruise on the motorcycle, especially on such a curvy road. Motorcycles have better acceleration, maneuverability, and they can corner better and at faster speeds.
Corrected entry: In the scene at the BioCyte building, Ethan is lowered down to the lower floor through the atrium on a long rope. He then cuts the glass to the lab and descends even further down. After the gunfight Ethan escapes by base jumping through a hole in the wall. It appears that Ethan is now at least 40 stories in the air, not the basement as we were led to believe.
Corrected entry: In the BioCyte lab, a maximum security alert goes off and a wave of say ten guards runs up the stairs and are killed by Ambrose's men. The action then stops so Tom Cruise can run out and Ambrose's guards look out the hole he blew. Are we supposed to believe that a maximum security alert is going to last two minutes with only one wave of guards?
Corrected entry: The position of Ambrose's body changes from when Ethan has knocked him out, to when Ethan takes the antidote from his jacket pocket (you can glimpse Ambrose's body in the background), and again, back to his original position when he pulls a gun on Ethan. Plus, the rock that his head was propped up on disappears.
Corrected entry: At the end, when Tom Cruise throws the knife at Dougray Scott's feet, there is a quick succession of shots consisting of the two in a fistfight. In one of the quick shots, there is a distinct black shape at the bottom right side of the screen that belongs to neither Cruise or Scott. The shoulder of a crewman who got a little too close, perhaps?
Corrected entry: The man who Hunt's team tricks into thinking he has Chimera is allegedly somewhat knowledgeable about viruses and yet alludes to penicillin as a previous wonder drug in the fight against them. Penicillin has NO effect on viruses, it works on bacteria. Similarly, Nyah is likened to being another 'Typhoid Mary'.. another misplaced bacterial reference.
Corrected entry: The main villain in this film (Ambrose) is supposed to be an active IMF Agent. A CIA operative can't apply for an auto loan without his superiors finding out, but a high-level agent of an entirely black-ops agency with the resources of the IMF can go completely evil, hire a subservient lacky and a whole army of henchmen, own a whole fleet of autos and motorcycles and an arsenal of explosives and weaponry, and the IMF has NO idea whatsoever until he crashes the plane (a task that would take extensive planning)? The movie seems to completely ignore the fact that this guy is a current employee of the US government and not some international criminal.
Corrected entry: The scientist who injected himself with the Chimera virus decided to cut things way too close. He says in the video that he must travel from Sydney to Atlanta in less than 20 hours. He is then shown flying on commercial airlines. A flight from Sydney to LA takes 15 hours, and a flight from LA to Atlanta takes 5 hours. He didn't leave himself any time at all for error or delays.
Corrected entry: Throughout the film, Ambrose has relatively short hair (on the back of his neck). But at the horse-racing scene at the beginning of the film, you can see that his hair at the back of his neck is exceptionally longer than at any other point in the movie.
Corrected entry: At the end of the movie when Tom kicks the gun from the sand, firstly, it would be impossible to kick the gun so that it flies directly vertical from where it lies, secondly if you look closely, you can see the 'fishing line' that is attached to the gun to make it fly up vertically.
Corrected entry: After Ambrose realises that he has just shot Hugh Stamp, there is a car chase, where Hunt shoots at a bronze coloured car. If you look closely you can see that it is in fact Hugh Stamp driving, though he died minutes before.
Corrected entry: When the 2 Triumph bikes square off on the beach, just before they race towards each other Tom & Dougray rev their bikes. It's a really fast cut between the two throttles but Dougray twists his left wrist, which does nothing on a bike.
Corrected entry: At one point we saw the memory card for the camera up close and it read '2 MB' on it. Later we see the contents of this memory card which is a complex animated video. 2 MB would be no where near enough to store the showed video sequence.
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: You know women, mate. Like monkeys, they are - won't let go of one branch until they've got hold of the next.
