The Kojak meeting Father Dimitrius church scene in Manhattan was filmed at the Saint Sophia Greek Orthodox Cathedral in Los Angeles. In real life, Telly Savalas was a member of the congregation. His funeral was held January 25, 1994.
Telly Savalas sings the title song at the beginning of the episode (reprised over the ending) and George Savalas' voice can be heard singing in a scene set in a church. Both vocal contributions are uncredited in this episode.
The relationship between Nico Trifores (George Pan Andreas) and Katrina Patropolous (Rhoda Gemignani) is inferred to be that of a younger man and an older woman. In reality, Rhoda Gemignani is only one year and two months older than George Pan Andreas.
