Continuity mistake: Dr. Kleinemann sometimes has a blue note paper in his left hand or not as the shots change while he talks with Major Hoffmann about Tony and Doug.
Continuity mistake: When Dr. Kleinemann snaps Doug's photo, Doug's face, eyes, and shoulders are square with the front of the camera. Later, when Kleinemann is brainwashing Doug, the picture taken shows Doug with his head turned to the right, not straight on with the camera.
Continuity mistake: After receiving the message from the radio, one of the resistance members levels his pistol at Tony, but the next instant cut shows the pistol held lower.
