After bombing the enemy airfield, three survivors of the British commando team are hiding behind some rocks above a mountain road. On the road below a group of enemy soldiers appear before the bend in the road. They are barely visible (1:25:40). A few seconds later the group of enemy soldiers have passed the bend in the road and they are very near and clearly visible (1:25:46). The camera pans away from them and a few seconds later when it pans back to the group of enemy soldiers, the group is again before the bend in the road, far away and barely visible (1:25:48).

The name of the Greek submarine captain is Nikolides Papadopoulos. These are both surnames in Greek. The correct name should be Nikos (Nick) Papadopoulos. Also the name Patroklis doesn't exist in Greek, even as a dialect. This should be Patroklos, which is used extremely rarely in Greek, and certainly not on an island.

As the team trudges through the mountains, one of the matte painted rocks moves with the camera as it pans.

Regularly throughout the film, German troops are armed with British weapons. For example, just after the commandos leave the submarine, a sentry is seen standing a post at an airfield with a British No.4 MK1 .303 rifle slung on his shoulder. Whilst soldiers did use captured enemy weapons, it is highly unlikely in this situation.

At 00:38:00 Denholm Elliott is handed the Thompson sub-machine gun the magazine fall off.

The officers are shown wearing SAS parachute badges on their right arms, as they do today; however, during WW2 they wore them on the left breast.

As Marika, the boys and the priest on a donkey approach the team when they are hiding in the night-time mountains a kookaburra and Pacific tree frogs can be heard, neither of which are native to Rhodes.

Just before the opening credits, the boy ostensibly playing the pipe stops moving his fingers whilst the pipe music continues.

When the two men are treading water awaiting the submarine, the shadow of the camera and crew falls on their faces at times.
