Continuity: The tyres on the crotch rocket motorcycles they were riding kept changing from knobbly tires 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.

Factual error: In the scene at the race track where they show the virus infecting and destroying cells in the blood stream, they clearly show that it is red blood cells being infected. Viruses, in order to replicate, reqire the cell's DNA replication machinery. However, mature red blood cells in the circulation no longer possess this machinery since they no longer have a nucleus or DNA. It would therefore be impossible for this virus to replicate.

Continuity: Tom Cruise is chasing Thandie Newton in his car in an early scene. He tries to fasten his seatbelt, and finally manages it. But later, sometimes he has his seatbelt on, and sometimes he doesn't.

Continuity: In the car chase scene with Nyah after they split and hit again and are spinning look at Ethan's car. The driver's side in the close ups was on the American side, then in the spin it is reversed to an English side. (It is a negative image - the license plate is reversed). The next image is back to normal.

Continuity: The registration plate on Ethan Hunt's bike changes between 'NI 89' and 'ND 69' on occasion. Clearest moments are NI 89 just as he goes into the flames on the burning bridge, and ND 69 when he's through them.

Continuity: In the scene where Hunt is chasing Nyah in the car, there is a part where he almost hits a gray car. When the camera shot comes from behind, we see a gravel road on the side with pine trees, but when it cuts immediately to an air shot, we see a concrete bridge-like road with no gravel for several feet ahead or behind. It does this throughout the scene.

Visible crew/equipment: Near the end of the movie, when the point of the knife is close to Tom Cruise's eye, you can see the cameraman and the reflector on the reflection of the eye.

Visible crew/equipment: When the cars flip over as they blow up, you will see a circular object underneath the vehicles, about the size of a tyre (very obvious in slow motion). This is the device that "lifts" the vehicle for it to flip on one side, timed with the appropriate explosion.

Continuity: During the fight between Ethan and Sean, Sean cuts Ethan's face with a knife and it's bleeding. A little bit later it is not bloody and it looks as if the wound is closed, then open and bloody again.

Revealing: During the scene on the beach just after the collision of the two bikes we see Scott and Cruise flying together in a big hug, but if you see the short shot when the black bike starts to explode frame by frame you will actually see a lonely man with his arms wide open.

Factual error: The action takes place in Seville, and the burning of wooden figures is shown as a traditional feast. The feast involving the burning of wooden figures takes place in Alicante and Valencia, 350 miles way from Seville.

Continuity: In the rock climbing scene, just after Hunt does his flying jump, he falls, slides down a smooth rock face and grabs a hold at the last minute to stop him plummeting to his death. When he pulls back up, and over he grabs a hand hold on the smooth surface which wasn't their before. If you know what you are looking for, you will also see that it is a bolt on hold which has been attached to the rock face.

Continuity: When Nyah and Ethan are in bed in Spain, the lights reflected off Etahn's face and of the bed covers change between shots.

Factual error: The emergency gas masks in a 747 are not linked to one sole system, which can be poisoned. The masks are connected to individual oxygen producing containers.

Factual error: In the scene where Ethan is in the helicopter about to rappel into the BioCyte building, you see his hair blowing upward. In reality, the prop wash from the helicopter would make his hair blow into his face.

Continuity: At the beginning when Ethan is getting briefed of his mission with the sunglasses, his point of view shot through the glasses shows the landscape moving across from right to left, yet on the shots looking at him he isn't turning around or moving his head at all.

Continuity: In the scene where Nyah is walking up towards Ambrose's house, the wind is playing havoc with Nyah's hair and scarf. Throughout the scene, there are several shots of her where there is no wind, her hair is not moving and the scarf is perfectly placed (most noticeably when she steps off the boat onto the walkway).

Continuity: When Ethan finishes showing Nyah the pictures of the aeroplane crash so she can see what kind of man Ambrose is, she puts out a candle with her hand.  Then when they show her from the front, it's lit again, from the side it's out, then lit from the front, AGAIN!

Continuity: In the scene where Nyah and Ethan have a race with a Porsche and an Audi-TT, at the end after the camera shows Nyah's feet you see both cars from front. Now on the right side of the screen you see the shadow of the filming helicopter.

Continuity: Why did Hunt's team decide to use an outback location as their Sydney base? It looks like its in the middle of the Nullabor, which ain't exactly a helicopter ride from Sydney. Come to think of it, there isn't much terrain like that anywhere within a several hundred kilometres of Sydney.
