Continuity mistake: When Nyah is getting out of the "PALACIO DE JUSTICIA" building in Sevilla Spain, she is using a leather bag in her right arm, then we see a close up of Tom Cruise wearing sunglasses and watching her. The reflection of Nyah on the sunglasses is wrong, it should be backwards (the bag has to be in the left arm in the reflection).
Continuity mistake: Ethan shoots the glass on the front of the black bike during the chase near the end, but when the bike lands after jumping off the rock over Ethan, the glass is back in perfect condition.
Continuity mistake: After the car chase, when Nyah sits in Etahn's lap, the sun is on the left side of her face (and from the back right on Ethan). In the next clip Nyah's face is in shadow and the sun is from the front left on Ethan's face.
Continuity mistake: In the first car chase, in the clip right after Nyah says '. you gotta catch me', you see the double yellow lines on the road. But in previous clips, and on the clip right after, the lines on the road are white. The clip with yellow lines are from another stretch of road.
Continuity mistake: In the final fight scene between Hunt and Ambrose, Ambrose cuts Hunt's face and back with his knife. But in the scene when the knife is close to his eye, you get a close up of it and there is no blood on the knife blade. It is perfectly clean.
Continuity mistake: When Tom and Thandie are lying in bed after the chase, at the end of the scene, he leans in to kiss her. Thandie brushes back a very clear lock of hair that has come out of nowhere.
Continuity mistake: The agreed ransom at the start of the film is £37 million. Later this turns into 30 million pounds (though I may have got the share options bit a bit confused here). Then when the transfer is actually made, it has reduced to 30 million dollars.
Continuity mistake: In the rock climbing scene at the very beginning of the film, you can see the magnesium dirt left on the rocks from the earlier takes.
Continuity mistake: When Nyah is informed that the disc is in an envelope in Sean's pocket, she takes it out and puts it under her arm with part of it sticking out on the back side of her arm. The scene changes to a half body shot of Nyah and you can tell there is no envelope under her arm and as she turned to walk away Sean would have seen the envelope sticking out from under her arm.
Continuity mistake: As Tom Cruise is climbing up to the biotech island facility, the helicopter is sat waiting on a ledge. As the camera helicopter flies around the stationary chopper, its downwash causes one of the rotor blades to bounce downwards momentarily.
Continuity mistake: When Ethan kills Ambrose his head lays on a rock. A shot later, half a second afterwards from a wider angle, it's on the sand facing the opposite way. Then a shot later back to the first close-up and it's lying back on the rock.
Continuity mistake: At the end when the helicopter swings in front of the woman on the cliff, the damage to the left side of the helicopter is missing - bullet holes, broken glass etc.
Continuity mistake: Near the start of the car chase at the end, a white car loses a hub cap in extreme close-up, but when it wipes out completely and flips over a few seconds later all its hub caps are still on.
Continuity mistake: During the end bike chase scene, Ethan Hunt has just used his mirror to fire his Beretta at Sean Ambrose, he then re-holsters the weapon and swerves round two cars. If you play the movie slowly you can see that after he re-holsters the gun it is still in his left hand while he is holding onto the handlebars. It's a quick shot so you have to look carefully.
Continuity mistake: When Sean removes his Ethan mask on the 747 his eyes change from Ethan's clear blue to his own dark. But there is no eye cover or contact lenses incorporated in the mask. (00:04:40)
Continuity mistake: At the rock climbing sequence, after he slips and is hanging by one hand starts staring at the landscape, in the wide shots, the sun is directly behind him, but in the closeup shots, he is in the shadow. (00:07:45)
Continuity mistake: During the motorcycle scene near the end of the movie there is a shot of Cruise from the front. You can clearly see an earring on his left ear. A second later it's gone.
