The co-creator of MASH’s failed sequel AfterMASH once hilariously summarized why it bombed so completely. Despite MASH having run for 11 seasons, it was still a ratings hit for CBS when it ended. This led the network to greenlight some ill-advised MASH spinoffs, with AfterMASH being the first. This saw returning characters like Potter (Harry Morgan), Klinger (Jamie Farr), and Father Mulcahy (William Christopher) working together in a Veteran’s hospital after the war ended; the resulting series was a total disaster, as was the second failed spinoff, W*A*L*T*E*R.
