Culp continued to find steady work on television for the next several years and was eventually paired with funnyman Bill Cosby for the groundbreaking series "I Spy" (1965-68). Scoring Best Actor Emmy nods for each of the show's three seasons, Culp always lost to his co-star. He later earned a new generation of fans in the 1980s playing the slightly unhinged Bill Maxwell on "The Greatest American Hero."
Among Culp's memorable film credits are Bob & Carol & Ted & Alice (1969), Hannie Caulder (1971) and The Pelican Brief (1993). He died March 24, 2010.
