The Other Marty: Fairuza Balk originally played the FBI Agent Deborah Ciccerone in "Army of One", and the initial broadcast kept her scenes. However, as she could not reprise the role for the character's later planned appearances (due to scheduling conflicts), her scenes were quickly reshot with a replacement actress, Lola Glaudini. The reruns of the episode and the DVD release use the replacement scenes to keep continuity with the character's later role.
