Artemus Gordon (Ross Martin) is nursing a broken leg in this program. On June 26, 1968, during filming of "The Night of the Avaricious Actuary," whose broadcast date was pushed out December of that year, Martin broke the fibula of his right leg during filming of an action sequence in which fired a Colt repeater with pump handle and, after tossing it aside, caromed back and he accidentally stepped on the barrel, rolled his foot over it, and instantly broke it. As a result, the script for the next program filmed, "The Night of the Juggernaut," was re-written to have Martin's character suffering a leg injury. The injury was worked into a few subsequent shows while Martin recovered. A lot of Martin's on screen minutes during his recovery are spent sitting down or stationary. Fortunately, Martin was a quick healer. Three weeks after the accident, the cast was removed and by the end of the week, Martin was back driving again. As it happened, the scene in which Martin was injured was finished later after the he was able to move around and walk again.
