Kate Burton plays Erica Gardner in this episode and three others, but she previously played the role of Sister Bettina in episode 2.17, Sisters of Mercy (1992).
Andrew Pang has portrayed five different characters throughout the course of the series:
- Episode 20.9 For the Defense (2009) - Judge Gus Ishikawa
- Episode 12.2 Armed Forces (2001) - Bao
- Episode 8.4 Harvest (1997) - Dr. Hsu
- Episode 6.18 Atonement (1996) - Mr. Nakiyama
- Episode 5.17 Act of God (1995) - Mr. Kee
At one point point Lt. Van Buren mentions the "famous blue Audi" that Bart Rainey was driving the day Maggie Hayes was killed. This appears to be an oblique reference to the Leonard Cohen song "Famous Blue Raincoat".
