Continuity mistake: When the team are about to jump from the cable car into the river, the view from ground level shows a bare road with no snow on it on the right and a line of trees on the left with German trucks parked next to them, but the view from the cable car shows a snow-covered road and no trucks beside the trees.
Continuity mistake: When Smith and Schaffer intrude on Carnaby's interrogation, the Gestapo officer and Mary are having drinks in the café, where he makes a statement that might reveal a fault in her identity (a location in Dusseldorf). Her hand is fixed on her chin, but the next cut shows her hand fully on her cheek.
Continuity mistake: When the team is about to jump from the cable car into the river, seen from the cable car, they wait until they get close to the shore. But when they jump, seen from below, the cable car is moving across the river from the far side, and they land in the middle.

Continuity mistake: The car that Schaffer and Smith are riding in with the Germans is launched in the air by hitting a pile of snow and then comes to a sudden stop by hitting a pile of gravel where the Germans are killed. What happened to the pile of snow when Schaffer and Smith push the car backwards?
Continuity mistake: In the scene where the Germans are beating down the door to the hallway leading to the cable car, when the door is about to give way, in the clip from inside the door, it is moving a lot under each blow, but when seen from the outside it doesn't move at all.

Continuity mistake: In the scene where the group parachutes in, the sky is cloudy and we can see snowfall, but watch carefully, as the men make their way to the equipment containers and then to find Sgt Harod we constantly see shots switching between cloudy and snowfall, then to no snowfall and sometimes sunlight, then back to cloudy and snowfall again. This switch back and forth is even more evident on the closeups of Richard Burton.
Continuity mistake: After looking at the Castle, Smith sends Shaffer back to the others to tell them to stay behind the tree line and he goes to the radio to contact London. When he turns to go to the radio his MP40 has the butt extended, but when he gets to the radio it's folded back again.
Continuity mistake: During this sequence at the radio transmitter in Admiral Rolland's headquarters, whilst the Admiral is attempting to regain contact with Smith, Colonel Turner is seen in the background, smoking. At the beginning of the sequence, one shot shows him holding a cigarette between the fingers of his right hand. After a cut back to the Admiral, the next shot shows Turner holding the cigarette in the fingers of his left hand.
