Cannell was trying to avoid save-the-day-type episodes, as per the original "Adventures of Superman" television series, but according to Cannell on the DVD set, when Carsey and Werner left ABC (soon after the show was purchased by the network) the new network executives wanted the show to be more like a children's show than an adults' show. So they pushed for the types of shows that Cannell did not want, shows that involved Ralph trying to stop some sort of calamity from happening, including nuclear war ("Operation Spoilsport") and even a Loch Ness Monster-type of creature ("The Devil in the Deep Blue Sea"). For the season two finale, a serious and appropriate for the time (considering the Cold War) episode was produced; "Lilacs, Mr. Maxwell", written and directed by Robert Culp. The episode story concerns a KGB mole-agent (played by guest actor Dixie Carter) placed into the FBI with the sole purpose of discovering the methods used by agent Bill Maxwell in catching spies and other assorted villains. Cannell gave Culp free rein to produce the episode.
