 The cab scene on Washington and Cherry Streets in San Francisco  could not be entirely shot in San Francisco due to filming  restrictions and the opposition of the neighborhood residents. So, a  set of the intersection, including the street, apartments and crime  scene was constructed at Downey Studios just outside of Los Angeles,  California. Backdrops of San Francisco were digitally inserted to  complete the scene. Only a few seconds of actual footage shot in the  original crime scene location remains in the scene.
