Several folks who watched that clip from The Secret World of Og have written to ask about (or compliment my E.S.P. about) the name of Lucy Lawless. In the clip from '83, one of the characters mentions her passion for Lucy Lawless novels…and of course, a decade or so later, an actress named Lucy Lawless became quite famous, particularly for playing the title role on the TV series, Xena: Warrior Princess.
I did not predict Lucy Lawless. Pierre Berton used the name in the 1961 book I adapted. I gather Lucy Lawless was supposed to be a mystery-solver in the grand tradition of Nancy Drew.
According to Wikipedia, which as we all know is never wrong, Lucille Ryan married Garth Lawless in 1988 and kept his surname after they divorced. So that's how she became Lucy Lawless. Just a co-inky-dink.
