His father was/is quite old fashioned.
That's probably true, but ron howard basically grew up on the set of the Andy Griffith show, and as I stated in reply #15, the lady who played Clara Edwards did appear in Rosemary's Baby, shouting "hail satan".
I know, I know, she's an actress and saying her lines, blah, blah, blah.
It creeped me out, though, when I saw that watching the movie on AMC.
BTW just for some historical perspective, the Taylors in the Andy Griffith show, were Protestants(the writers never did say which sect) and IMO, kinda of mirrors what has happened in "mainline" Protestant churches since the 1960's(i.e the Episcopalians, Methodists, etc.etc.) having fights over doctrine and losing members.
