Michael Knight walks into a bar and orders a zombie cocktail. Sitting in a booth behind Michael is Ken Foree, one of the stars of George Romero's classic 1978 zombie movie "Dawn of the Dead".
Filmed, but cut from the episode, is Michael's brief encounter with Carmen, "a pretty dark-haired girl." Jean Lubin still receives credit for the role.
The scene in which Michael is suspended is extended in the script. Devon informs Michael that whatever he intends to do "will have to be without Kitt." They part company on slightly better terms than in the episode.
According to the script, the entry-code to the Foundation garage is 2-1-6-7, although the episode switches this to a palm-print readout. The original code for the Fire Mountain vault was 3-2-8-1 (it's 3-2-8-0 in the show).
K.I.T.T.'s punchline in the Tag ("Given a choice, I prefer alligators") was added late in production. According to the shooting script, Michael and Bonnie laugh at Chuck's line "Little buddy, look who's here."
