When Tony and Rhodes leave the Mandarin's mansion, Tony has blood on his left eye and cheek, which changes to the other eye between shots, then changes again at the boat.

At one point Khan threatens to target the Enterprise's life support systems which are located behind her "aft nacelle". The Enterprise doesn't have an aft nacelle; as the many exterior shots show, it has a port nacelle and a starboard nacelle. This isn't even believable as a character mistake, since Khan a) is familiar enough with Starfleet ships to know this basic fact about the Enterprise, and b) can see its nacelles for himself on his own viewscreen while he's delivering this line.

The wound on Jack's nose changes throughout the film.

The excavator Bond uses on the train has walking platforms welded to the top of the digging arm, they are not a feature of the machine but necessary if you are going to have your actor run up the arm.

In the scene where the Swissair 747 is taking off from Tehran the police cars keep up with the plane until it lifts off. Takeoff speed for a 747 is about 160 mph so the police cars would have been far behind by then.

When Jack reverses aggressively out of the motel carpark onto the road, he steers the car to his left and drives down the road. Note that there are no visible tyre marks left by Jack's car as he drives away. In the next shot, the police cars exit the carpark sliding out onto the road to their right, following tyre marks which are already on the road. The tyre marks on the road are likely from a prior take.
