Factual error: When Sally and Bryan are in the street, we can see, at their back, election posters. These posters appeared in 1932, one year after the movie is supposed to take place.

Continuity: During the song "Money, Money", Sally (who is singing with Emcee) 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.
