Continuity: When the group goes to the diner after their first class, When Bobby takes off her hair piece clip and puts it back on, at first it's smooth then when the shot changes, it's all messed up.

Factual error: In Shall We Dance, there is a mistake regarding the El (elevated train) stop sequence portrayed. When Richard Gere's character jumps off the train to check out Miss Mitzie's Dance Studio, the announcer says "next stop Sedgwick". However, we see that the train is at a stop that has three lines including the orange (as noted by the colors on the column on the left of the screen). The two stops that are before and after Sedgwick don't have the orange line so it's not possible for the next stop to be Sedgwick.
