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 mistake: In the final scene when Velma and Roxie are performing, there is lipstick on Roxie's teeth. In the next shot it has disappeared. (01:41:35)
Trivia: Hunyák's story in the cell block tango (translated from Hungarian) is "What am I doing here? They say my famous lover held down my husband while I chopped off his head. But it isn't true, I am innocent. I don't know why Uncle Sam says I did it. I tried to explain it at the police station but they did not understand me."
Velma Kelly: Well, you wanted my advice, right? Whatever it is, don't forget Billy Flinn's number-one client is Billy Flynn.
Question: How much time supposedly elapses between Roxie's arrest and her being acquitted of the murder charge? I have a hard time with the "fake pregnancy" element. We know Roxie was faking it, but if at least a few months had passed between her arrest and her announcement - much less between her trial and arrest - she was so thin that even a pregnancy of a few months (or lack thereof) would be noticeable to anyone who looked at her.Kimberly Klaus
