This is the first of five appearances Cyril Delevanti makes in this series, each time playing a bit part as an attendant of some kind, flop house, men's room, newsstand, etc.
This is the first of three appearances Norma Crane makes in the series. She plays a different character in each appearance and shares a tenuous connection between the characters she plays in her next two appearances vis-à-vis the relationship those characters have to the character Legs Diamond, cf. Jack 'Legs' Diamond (1960) and The Lily Dallas Story (1961).
This is the first of three appearances Harry Dean Stanton makes in the series, each time playing a different character. His other two appearances occur in Augie 'The Banker' Ciamino (1961) and 90-Proof Dame (1961).
