Insight was a staple of Sunday morning programming in many cities, though some would also air the show in late night, for 23 seasons (1960-83). A religious-themed anthology series that attracted a host of well known stars, including John Astin, Edward Asner, Patty Duke Astin, Efrem Zimbalist, Jr., Jack Albertson, Ron Howard, and so many more.
Father Elwood Kieser was the show's executive producer and host for most of its run. Kieser also attracted two well known writers in Michael Crichton and Twilight Zone creator Rod Serling, one of the most prolific writers of his era.
We have one episode over at Saturday Morning Archives from 1975 with Bob Hastings (ex-McHale's Navy; he was recurring on All in The Family by '75). Here, though, is "Leroy", from 1977, with Albert Salmi (ex-Daniel Boone) as an illiterate homeowner who's lost his house because of his inability to read a medical bill. James Doohan (ex-Star Trek) is the buyer, a real estate mogul. Co-starring Roscoe Orman (Sesame Street).
