Trivia: Since Kolchak revealed in "The Spanish Moss Murders" that his greatest fear is dentists, it's ironic that Bella Sarkof picks a dental assistant as Kolchak's ideal mate.
Why didn't the police just identify the bodies by their fingerprints? Or maybe they did and hushed it up...
Kolchak: (opening narration) Nowhere in man's history does he display more tenacity, more perseverance, than in his search for eternal youth. Halting the relentless process of aging has been a constant dream of man's...and woman's. Eternal youth - is it really a dream, or is it possible that somewhere someone found the secret? The following experience gave me a new attitude on the whole subject of youth and aging.
This is Ruth McDevitt's last appearance as Miss Emily as well.
This is Jack Grinnage's last appearance as Ron Updyke - according to Mr. Grinnage he was approached to do a guest appearance on another series and by this time word was out that Kolchak was being cancelled.
This is John Fiedler's last appearance of three as Gordy the Ghoul. This means this episode is tied with "They Have Been..." for most main/recurring characters in one episode - Carole Ann Susi doesn't appear here but Ruth McDevitt didn't appear in that episode.
