Actor Vincent D'onofrio who played Detective Robert Goren came up with the movement of leaning down low and to the side in the interrogation room (which became a trademark of the character) because guest star Lenny Venito (who played Jake Nathan) wouldn't make eye contact during their scenes.
The dates shown between scenes (e.g., Wednesday January 21) correspond to the year 1998, three years prior to when the show aired.
When Gia gets out of the lawyer's car after being released, a red pickup truck with two guys in it is visible. They roll down their window and wave at the camera.
The New York tag number of Goren and Eames' black Ford SUV is ESD 831.
