Continuity mistake: In the scene where Kevin Bacon and Laurence Fishburne go to Tim Robbins' house to speak to him about being in the bar on the night of the murder, they all walk down the street together, as Dave is walking his son to school. In one shot, following the men from behind, it shows them walking past a red brick building, then a blue cape cod style building.
