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)
