Mrs. Schumacher has a painting on her wall of her bichon frisé, Freddy. She was watching on her TV Royal Wedding (1951), starring Jane Powell and Fred Astaire (the "Did you get stood up?" scene).
4 years prior to shooting this, Tzi Ma (Li Chen) and Ken Leung (Tommy Wong) portrayed major characters in the comedy Rush Hour (1998).
Ken Leung has portrayed four different episodes over the course of the series:
- Episode 5.12 Progeny (1995) - Forensic Technician Chung.
- Episode 6.4 Jeopardy (1995) - Forensic Technician Chung.
- Episode 10.21 Narcosis (2000) - Stephen Wong.
- Episode 13.9 The Wheel (2002) - Tommy Wong.
This episode appears to be based on two separate cases/incidents:
- The persecution of the Falun Gong spiritual practice.
- The Gang Lu case.
Ironically three years later, Tzi Ma would play a high-ranking member of an LA Chinese Counsul who would investigate (and later become a freedom fighting terrorist) after the death of a Counsulate member.
