William Christopher, most famous as Father Mulcahy on “M*A*S*H” and “AfterMASH”.
(My mother observed that she saw him recently on a “Murder She Wrote” rerun, in which he was the bad guy. It looks like he knocked around a bit before “MASH”:
(And I was reading up a little on “AFterMASH” over the weekend. Yes, it was probably a bad idea in retrospect: even the executive producer thinks so, though I disagree with his assertion that it featured “the three weakest characters”: I don’t think he gives Harry Morgan enough credit.
But the thing that surprises me (I never watched an episode) is that it was actually a top 10 show in the first season. The thing that killed it wasn’t quality, or the lack thereof: it was that CBS, in their infinite wisdom, decided “AfterMASH” could go head-to-head against “The A-Team” for the second season. That…didn’t quite work.)
