Other mistake: When Travis is negotiating with Sport for Iris' services, an off-screen crew member can be heard saying, "but no rough stuff" just before Sport says it. (01:17:00)
Other mistake: Although the Lieutenant is actually sent to the police station in precinct 9, division 13, the sign over the door states it to be division 14.
Other mistake: In the beginning of the movie, the radio announcer says it is 74 degrees with a high of 89 degrees expected. The guy directing the oil truck breath is visible and is wearing a winter coat, not very likely at that temperature. People walking the streets are too heavily dressed also.
Other mistake: In one scene, the mayor of San Francisco and his aide go to a Giants baseball game at Candlestick Park. When the mayor and the aide are seated while having a conversation, a young man sitting a row or two behind the mayor leans slightly forward, looks directly into the camera, and starts smiling and waving.
Other mistake: Legendary wrestler Antonino Rocca makes a cameo appearance in the movie. He is, as correctly listed in the closing credits, one of the "Funeral Attendants" together with Michael Weil. However in the opening credits he was specifically billed as the Funeral Director, which is Ronald Willoughby's role as correctly listed in the end credits. (00:00:50 - 01:45:15)
