First mentioned in this episode, one of the ongoing plots in season 6 is the trial of the "Showbiz Madam." This mirrors the infamous real-life saga of Heidi Fleiss, popularly referred to as the "Hollywood Madam," who ran a prostitution ring in Hollywood for high-end celebrity clients.
Darryl Sivad portrays the fireman in this episode. This is his 3rd appearance and 3rd different character in the series. He previously played a paramedic in season 4 episode 10 Home Is Where the Heart Attack Is (1993), and a forest ranger in season 4 episode 21 The Harder They Fall (1994). Oddly enough, all 3 characters he's played have been first responders.
