Continuity mistake: Fiona Fullerton's eyebrows change from full to plucked and back again all through the film.
Continuity mistake: Near the end of "The Lees of Old Virginia," Richard Henry Lee is seated on a water fountain, and then stands up. In the following shot from behind, he is back on the fountain and stands up again.
Continuity mistake: During the song "Money, Money", Sally (who is singing with the Master of Ceremonies) has nail polish on. This changes color throughout the song, and in the close-ups this becomes more obvious. At the beginning of the song we see that it is green. Later, while we hear, "You can take it on the chin" we see that it has changed color to red. In the end of the song, while "It makes the world go round" it has returned to green.
