Pierre Watkin played Perry White in a pair of movie serials, "Superman" (1948) and "Atom Man vs. Superman" (1950); when John Hamilton died following the sixth season of "The Adventures of Superman", Watkin was rumored to be in line for the role until the death of George Reeves killed the series. Also Pierre Watkin and Noel Neill reunite since the "Superman" 1948 serials: Watkin as Perry White and Neill as Lois Lane.
At the time this episode aired, Ron Foster and Morgan Windbiel (who play the two unnamed policemen) could also be regularly seen in the respective roles of Officers Garvey and Hoffman on the syndicated series Highway Patrol (1955).
