Actors Robert Rockwell and K Callan have a connection of sorts outside of this episode. Both of them had played one of Superman's parents in a television series, though not the same one. Robert Rockwell played baby Kal-El's Kryptonian father in the pilot episode of "The Adventures of Superman", titled "Superman On Earth". K Callan played Martha Kent on "Lois and Clark, The New Adventures Of Superman" for all four seasons.
