Revealing mistake: There is a short section where a U.S. soldier hops a rugged looking stone wall in France. As he goes over the wall, it moves back and forth a bit as if made of styrofoam and wood.
Revealing mistake: In the scene where Roddy McDowell shoots the machine gun nest, you see when he takes his first shot, the "dead" soldier next to him jumps when the gun goes off.
Revealing mistake: In the Orne bridge attack, a wounded British paratrooper rolls a grenade over the bridge wall to a walkway where some German soldiers are, the grenade landing in the middle of the walkway. The explosion of the grenade, however, comes from the bridge wall to the right, presumably where the pyrotechnics were placed for the grenade explosion.
Revealing mistake: In the very first scene, the tire tracks from the camera crew's vehicle are visible trailing behind as they follow the distance of the scene.
