Continuity mistake: After Moses accidentally kills the guard at the temple, someone points out Moses as the killer and they point straight up. However, we see a shot from behind Moses while he stares at the fallen guard and the angle in that shot between where Moses stands and the fallen guard and the crowd around him is inconsistent with the scene where someone points Moses out. The body and group have moved from just below the scaffolding to several feet away.
Continuity mistake: On the marquee that advertises the show "Band Wagon", the name of the actress is listed as Gabrielle "Girard", but when the scene switches to a shot of someone holding the program for the show, her name on several pages of the program is spelled Gabirelle "Gerard".
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 they are trying to find the stolen bus, they have that radar thing. In one shot the thing is showing that they should turn right yet they say left and go to the left.
Continuity mistake: Early in the movie when Thomas falls overboard, John Smith ties a rope around his waist (00:02:56) and jumps in after him. Thomas is very far away from the ship (00:03:12). But when the men pull John and Thomas up, John is holding on to the rope with one hand and the end is left dangling (00:03:36). One of the men who pulled them up then coils the rope with a mere two coils (00:03:48), not nearly long enough to have reached Thomas while he was overboard. In the same scene, when we are viewing the men pulling John and Thomas up from above (00:03:38) there is no extra rope at their feet as there should have been for such a long rope.
Continuity mistake: John Norman (Kris Kristofferson) and Esther Hoffman (Barbra Streisand) are sitting at the table talking. John opens a bottle of wine and every time the shot faces John the cap is on, but when the shot faces Esther the cap is off, over and over again.
