Real-Life Relative: In "Who's Woo in America," William Katt's real life mother, Barbara Hale, plays Ralph Hinkley's mother Paula.
Robert Culp's sons appear in "Vanity, Says the Preacher."
Screwed by the Network: Series creator and executive producer Stephen J. Cannell had envisioned The Greatest American Hero as a show focusing on down-to-earth, real life problems, the powers would be in the suit, not the guy (though the suit would only work for him) and Ralph would try to solve ordinary-type issues. The ABC executives whom Cannell had pitched the show to, Marcy Carsey and Tom Werner, had actually agreed to go along with this. Unfortunately, however, after the show was picked up, Carsey and Werner left ABC to create their own production company, and the new network executives demanded that Cannell incorporate more fantastic plots, which ultimately alienated viewers.
The final blow came when ABC moved it to Friday Nights. The ratings went down so fast four episodes were left unaired.
Throw It In: The scene of Ralph writing his name on the blackboard with the chalk breaking at the start of the third season's credits was a blooper.
Written andDirected by Cast Member: Robert Culp on "Lilacs, Mr. Maxwell", and "Vanity, Says the Preacher" (the latter was one of four episodes not shown in the network run, although it and the others did get shown in syndication- unlike the pilot for some reason).
