The two-season spin-off "AfterMASH" (1983–1985) inherited the parent show's Monday night time slot and featured several of its characters reunited in a Midwestern hospital after the war. The more successful "Trapper John, M.D." (1979–1986) took place nearly three decades after the events of "M*A*S*H" and depicted Trapper John McIntyre as chief of surgery at a San Francisco hospital; its producers argued successfully in court that it was based on the earlier movie rather than the TV series. In an unpurchased television pilot, "W*A*L*T*E*R" (1984), Walter "Radar" O'Reilly joins the St. Louis police force after his farm fails following his return to the U.S.
