In the script, Bianca is described as being "in her early thirties and devastatingly beautiful. A woman with an insatiable taste for adventure of all kinds."
In the script, Michael's disguise (Dr. Michael Knightwood) is described as "dressed sort of egg-headishly, and even wears rather unglamorous glasses. He definitely looks different." "Dr. Knightwood" has a PhD in Physics from the Washington University of Technology, his most recent publication was The Journal of Military Science. The subject matter was Star Wars Space Weaponry. In a cut scene that shows him preparing his cover, Michael tells K.I.T.T. that "Given the choice between a beautiful woman and a good floppy disc, I'll take the floppy disc anytime." K.I.T.T. doesn't believe a word of it.
Don Galloway also appeared in the episode WHITE BIRD. Ann Turkel previously appeared in the second season as the villainess Adrianne Margeaux, in the episodes SOUL SURVIVOR and GOLIATH RETURNS. Coincidentally, the location of Bianca's retreat was also home to Adrianne and Garthe Knight in Goliath Returns.
As "Junk Yard Dog" finished filming on 21 December 1984 the cast and crew obviously broke for Christmas , this episode was filmed after the break and "Buy Out" which was filmed starting 10 January 1985, we can surmise this episode was filmed between 27 Dec '84 and 7 Jan '85 (given they would need time to prepare for "Buy Out")
It is revealed in this episode that Tuflex-coated bullets can penetrate K.I.T.T.'s tires.
