It is the only television film where Lynda Carter has an antagonistic role.
This television film features eight deaths (six men and two women). Since an account book, Johnny's diary, and a key on Barbara Leguire's costume had no existences whatsoever, Barbara and Leora were both being dishonest along with Helen. Johnny, Carl, and Brad all believed them. That is what led to their unexpected deaths. Reggie and John only murdered Barbara, Bundy, and Leora.
Though Lynda Carter and Jim Carrey did not appear onscreen together in this television film, they both portrayed DC comic book characters. Lynda performed as the title character and her secret identity Diana Prince on Wonder Woman (1975) and Jim performed as Edward Nigma/The Riddler in Batman Forever (1995).
Michelle Phillips who portrayed Leora in this television film previously appeared in Murder Me, Murder You (1983) as Chris Jameson. Her death in that television film was Michael A. Andrews poisoning through tampered medication; she dies shortly afterwards while testifying in a courtroom. She was not seen taking the poisoned medication, but her apparent "heart attack" in court was shown on screen.
