More precisely, stars who flopped in series TV — Roddy McDowell did quite a bit of voice-over work and TV movies, for instance, but his three gigs as a series regular (Planet of the Apes, Fantastic Journey, Tales of the Gold Monkey) were all over in one season or less. And that’s not even counting his unsuccessful pilot Topper Returns or getting replaced as the voice of Niddler in Dark Water. None of which, as I note in the piece, reflects on his talent.
