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 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.
Trivia: "Cabaret" holds the record for most Academy Awards won by a film which did not win the Best Picture Award. The film won eight in total.
Brian Roberts: You're American.
Sally: Oh God, how depressing! You're meant to think I'm an international woman of mystery. I'm working on it like mad.
Master of Ceremonies: Outside it is windy, but inside it is so hot, every night we have ze battle to keep the girls from taking off all their clothing. So don't go away, who knows? Tonight we may lose the battle.
