Technically, this is the only episode of "Mission: Impossible" with no regular cast member involved in the mission. Steven Hill appears at the beginning, but his character, Daniel Briggs, excuses himself from participating because the subject of investigation knows him. The only two agents directly involved are Dr. Carlos Enero (Barry Atwater) and Rollin Hand (Martin Landau). Atwater was not a regular player; and although Landau appeared in nearly every episode of the first season, he was, for contractual reasons, always billed as a guest star.
The agent photo which Briggs rejects right after selecting Rollin for the mission, is actually a photo of Joseph Gantman who produced the first two seasons of the show.
This episode is unique of all the missions in which Briggs or Phelps is warned of the consequences should any of the team be caught or killed in that the word "disavow" is not used. Briggs is warned that the Secretary will *disclaim* any knowledge of the team's activities.
This was one time out of a few during the first season, when Martin Landau was the lead.
"Kinder, Kuchen,and Kirche" is German for Children, Kitchen, and Church.
