The cast boasts Star Trek (1966) alumni: John Colicos (Errand of Mercy (1967)), Nancy Kovack (A Private Little War (1968)), and Barry Russo (The Devil in the Dark (1967) and The Ultimate Computer (1968)).
The red-brick patio set used for Lytell's home would have been familiar to fans of the recently canceled series Longstreet (1971), where this same set served as the home of blind New Orleans insurance investigator Mike Longstreet (played by James Franciscus).
