Continuity mistake: When Roger is in the van talking to Macdonald, his face is deliberately dirty and stubbled - but when they are about to shoot him, he is clean-shaven. similarly with his bruises which seem to magically disappear by the evening of the first day.
Continuity mistake: Check out the memorable scene when Hendley and Blythe, trying to reach Switzerland in a stolen training aircraft, fly over marvellous Castle Neuschwanstein. According to Hendley, they've almost made it, just 20 minutes of flight and one mountain range left to cross. This is quite funny because the Neuschwanstein shot reveals that they're actually flying straight in the wrong direction. The camera faces south, the plane moves from right to left, meaning they're heading east, straight away from the Swiss border which is just 50 kilometers west of the famous castle.
Continuity mistake: In the end of the movie, Hilts (Steve McQueen) is returned to the camp - he is dirty and his shirt is torn. When he enters the cooler, after being tossed his baseball glove, he is clean and his shirt is no longer torn. (02:49:50)
Continuity mistake: In the scene in which the POWs are distributing the tunnel dirt over the compound, Hendley is leading a group of POWs in a soldier's march. In one shot, dirt is coming out from the bags inside their trousers, but their hands are visibly swinging back and forth; they can't be pulling the strings in their pockets to release the dirt. (00:53:50)
Suggested correction: The soldiers in the center of the group have the bags in their trousers and can pull the pins. The soldiers on the edge of the formation are blocking the view of the other soldiers from the guards and can swing their arms freely.
Continuity mistake: When Hendley and Blythe emergency-land their plane, it dashes into a copse. Both wings are cut off by trees and stay behind, while the fuselage runs on for several meters, finally coming to a halt with the tail facing down and the cockpit up. Next shot (pilots exiting the plane), the crash site looks very different: The tail now points into the air, cockpit down. And even worse, the wings have returned to the plane, I mean they are still cut off, but now positioned neatly on both sides of the fuselage instead of all those meters behind where you'd expect them.
Continuity mistake: In the scene where Steve McQueen is pulling wire across the road, and attaching the end to the pole to trip up the motorcycle rider you can clearly see two shadows on the ground of Steve in opposite directions due to the camera lights.
Continuity mistake: After Ramsay, Bartlett and MacDonald drink the American moonshine, Ramsay's collar and neck change between shots. (01:20:30)
Continuity mistake: When Blythe starts to lose his eye sight, he tests his eyes by closely examining the forged document. But the document he holds up is different from the document we see in the later shots.
Continuity mistake: When Hilts and Ives are put back in the cooler after their first escape attempt, the dirt on their faces in the corridor outside their cells doesn't show up in the same places when they are actually in their cells.
Continuity mistake: Just after Ashley-Pitt has worked out how to hide the dirt, we see Ramsay raking the dirt and Bartlett and MacDonald walk out from behind a building and look at him, but in the next shot, Bartlett and MacDonald are looking at each other.
Continuity mistake: When Bartlett is on the run in the town a car containing Germans pulls up near him. Bartlett stops on the pavement but in the next shot he is standing in the middle of the road. (02:31:57)
Continuity mistake: When Hilts draws his gun to shoot at the motorbikes, he steadies his gun-holding hand with his other hand, but in the next shot, he is holding his hand in a different way. (02:14:05)
Continuity mistake: The position of the propeller crank changes between when Hendley first hands it to Colin and when Colin begins to crank it.
Continuity mistake: When Willie is disguising the tunnel by mopping the floor and the Nazi comes in and bothers them, the way that Willie is holding the mop changes between shots. (00:44:10)
Continuity mistake: When Henley attacks the guard at the airport, the back of his jacket gets wet from rolling around on the ground fighting the guard (there are puddles visible). Yet a few moments later, when he is walking towards the plane, his jacket is dry. (Visible in widescreen DVD version - 2:25:26 to 2:25:56). (02:25:25 - 02:25:55)
Continuity mistake: In the scene where Ives attempts to climb over the barbed wire fence, a long shot shows Ives in foreground and a line of men, including Hilts, in the background. In this shot, Hilts notices Ives and begins to run towards him. In the next shot, a close up of the line, we see Hilts still standing motionless, before noticing Ives and beginning to run towards him. Again.
Continuity mistake: While describing the escape process, Roger says that "Tom will run north from the 105." He is interrupted, then says, "as I said, Tom will run north from 104."
Continuity mistake: In the scene where Roger, Mac, Danny, and Willie are trying to figure out how to dispose of the dirt from the escape tunnels, Willie's motionless hand on the tabletop jumps from the supine position to the prone position between shots. (00:51:10)
Continuity mistake: After Hilts is dismissed from the cooler for the second time, he tells Bartlett about his escape plan, to which Bartlett replies, "Is Ives going with you?" After he says this, his hands change position in relation to his mug. (01:04:05)
Continuity mistake: When Hendley and Blythe get into the German aircraft first, the cockpit is tiny and cramped, like you'd expect. However, when they cut to the studio-done flying scenes, it suddenly becomes much larger, nice and roomy.
