Trivia: When Barry is checking the results of his tests in the police lab, he turns to the computer to view the screen. The camera changes to see the screen, and for just a moment (just a few frames) we see what was on the screen before his results - a couple of stolen car reports, one of which is that of "Joliet Jake Blues" (from the Blues Brothers movie). And yes, the car and licence are the same as in the movie. I don't know what the connection is; I assume someone on the crew loved that movie. (01:12:00)
