After "MASH", Bowen returned to television and gained a fan following as Hamilton Majors Jr., the pleasantly snooty and supportive Ivy League boss of Herschel Bernardi on the TV sitcom "Arnie" (1970–72). He then joined the cast of "The Brian Keith Show", then returned to TV commercials and smaller movie roles. In 1976, Bowen appeared in the TV parody film "Tunnel Vision", doing a convincing Henry Kissinger impersonation that he was often asked to perform at parties around Hollywood. (The film featured a galaxy of comic stars including Chevy Chase, John Candy, Howard Hesseman and Joe Flaherty, but Bowen received top billing as the others were still relatively unknown at the time.) Bowen also played minor roles in such films as "Heaven Can Wait" (1978), "The Main Event" (1979) and "Zapped!" (1982).
