Continuity: In the final scene where Roxie and Velma are dancing in the concert hall, Roxie is on the right and Velma is on the left. The two images depicted here do not immediately follow one another in the film. Just before they jump around, there are closeups of Velma, then Roxie, during which they might have swapped sides. (Time)

Factual error: In the scene where Roxie is placed in the "paddy wagon" to be taken to Cook County Jail, the prosecutor refers to himself as District Attorney Harrison. However, the court system in Illinois doesn't have district attorneys; rather, they have state's attorneys. The original play by Maureen Watkins correctly calls him a state's attorney.

Continuity: In the final scene when Velma and Roxie are performing, there is lipstick on Roxie's teeth. In the next shot it has disappeared.

Factual error: As Roxie is being escorted into the murderers' row, Mama and Roxie pass Velma's cell. The dollar Velma gives Mama is a modern one.
