Both "Gordy the Ghoul" and Monique Marmelstein appear for the first time in this episode, and before it's over Kolchak puts Monique in a cab heading to Brooklyn. She's back by the next episode though.
This is one of only two episodes in the series in which Ron "Uptight" Updyke does not appear, the other is episode #20 "The Sentry".
Kolchak's informant "The Monk" appears here for the first and last time, he's never seen again during the show's run.
Alex Grasshoff directs his first of three episodes with "The Zombie", the others were #8 "Bad Medicine" and #10 "The Energy Eater".
Carl: (opening narration) Popular folklore would have us believe that there exists in the underworld ruthless men who fear nothing. This story should debunk that myth.

(about one of his informants)
Carl: The Monk was of a lower order. He had never taken the vows of poverty or silence.
(Carl narrates over a scene of Albert Berg having his spine turned to shrapnel.)
Carl: Bad as my problems were at that moment, they were nothing compared to those of Albert Berg.
