Factual error: At one point late in the film, Terry says she called in a favor to the "District Attorney" after Lim was arrested. In Chicago, where the film is set and where the arrest took place, there are State's Attorneys, not District Attorneys. Terry, a lawyer practicing in Chicago, would most definitely have known that.
Continuity mistake: When Bird's co-workers are attacking Lem when he comes out the bathroom, he's wearing boxers under his towel.
Continuity mistake: When Miles is playing piano during Faith's dance scene, the angle of the sun through the windows does not match the sunlight shown on the close up shots of the piano keys based on where the piano is in the apartment.
Visible crew/equipment: When Lem is sitting in the living room talking to Kenny at his house, a light from the camera is visible in the window behind them.
Answer: Yes, but it could have easily been both.
