The Magician's recurring atmosphere player (blonde, middle-aged lady) is here singled out in the audience by Mark Wilson to come assist on stage when he asks her to bring him an ashtray. Another extra helps with the illusion and she holds the ashtray for him until that man sets a piece of paper ablaze for a brief second.
Simmons mentions that Tony has a photographic memory. This had already been established in the pilot: that photographic memory of his is what had allowed him to sketch Lucian Baker, the deceased, after seeing him once, at the morgue.
The helicopter used in this production was a rare 1967 Fairchild-Hiller FH-1100 (N703E serial number 28). These are commonly mistaken for the popular Bell 206 JetRanger. These can be distinguished by the one-piece windshield area, the high mounted tail rotor and the longer curved exhaust pipes.
Lloyd Nolan also played Tom KAGEN in Outer Limits "Soldier" having a very similar character last name playing Charles KEEGAN here.
