Movie Pilot.
Did you know that the regular series was preceded by the two-hour pilot movie, which first aired back on March 30, 1974. Good move, we think!
Notable guest stars.
Quite a few actors, some were well-known at the time or went on to become uber famous, guest-starred on the show. Including Johnny Cash & June Carter Cash, Vera Miles, Peter Billingsley, and Anne Archer to name a few.
