Delighting audiences as he had trouble with his saddle, his gun, or a flirtatious frontierswoman, Taylor continued his antics on TV's "The Roy Rogers Show" in the 50s. His film credits began to diversify, though, including crime drama ("Crime Wave" 1954), comedy ("No Time for Sergeants" 1958, Capra's "A Hole in the Head" 1959) and theatrical adaptation ("Sweet Bird of Youth" 1962). He also brought rustic humor to his recurring roles of Ben, fix-it-shop owner Emmet's brother-in-law, on TV's "The Andy Griffith Show" and repairman Ed Hewley on the first season (1965-66) of "Please Don't Eat the Daisies". In 1967 he memorably played the man who helped bring down the title characters in Arthur Penn's landmark "Bonnie and Clyde".
Taylor never left the Western, though. As genre revisions became common, Taylor's leathery presence, often grizzled, came to embody the Old West not only as it was lived but how it had been represented onscreen. Sam Peckinpah used him thusly in "Major Dundee" (1965), "The Wild Bunch" (1969), "Junior Bonner" (1972) and "Pat Garrett and Billy the Kid" (1973), as did films ranging from "Death of a Gunfighter" (1969) to "Back to the Future III" (1990, credited as "saloon old timer"). Taylor was as busy as in the old days, with eight credits in 1976 alone. He was as amusing as ever as a toothless varmint in the revival series, "Bret Maverick" (1981-82) and in the TV western comedies "The Dooley Brothers" (1979) and "Once Upon a Texas Train" (1988). Well into his 80s Taylor still stole scenes as the grandfather in the feature country singer saga, "Falling from Grace" (1992).
