Michael Champion, an evil biker, would play one of this show's heroes, Michael Ironside's thugs in Total Recall.
While this is the first actual episode within the time-line to show the sand-dwelling creature Crivit, who pulls people into the sand, eating them, it was the banned episode, Breakout, that featured them first... although there we only saw them kill but didn't actual see them, like in this episode.
First time in the series when Diana is seen without her trademark visitor red uniform.
