Continuity mistake: In the scene where Gerald Tetley confronts Major Tetley (his father)and talks about how his father gave the order for three innocent men to be hanged. His father listens till Gerald finishes then walks to a door feeling guilty, opens it and goes inside the room. The shot is focused on the door. A shot rings out and the Major has killed himself. Meanwhile we still see the door, then it opens and within a second the shot goes back to Gerald. (01:10:10)

Continuity mistake: During the opening of "This Is the Army" [the stage musical], there is a large choir of men singing the opening number, "Some Dough For The Army Relief": from about the second row back, the men's mouths are moving appropriately for the lyrics they're singing, but much of the front row is singing with these obnoxious cheesy grins, not even bothering with more than the most feeble attempt at proper mouth movement. [This is painfully evident during the line "let him do what we had to do."]. (00:48:50)

Continuity mistake: In the scene where the tank crew meet up with the weary band of soldiers, Fred Clarkson (Lloyd Bridges) has a very distinctive graze on the right side of his forehead.
