Continuity: When Ethan's pal is in the helicopter and Ethan is escaping on the motorbike he fires a grenade launcher at the car - he misses the first time, gets the car the second time, but you can clearly see the bridge is made of wood - where the car gets blown up there's a big concrete/steel plate to support the bridge.

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: 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.

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: 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 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.
