Culp was primarily known as a television actor, appearing in a variety of anthologies and guest appearances dating back to the early 1950s. However, he is most known for two works. He is known for his role as Agent Kelly Robinson in the groundbreaking I Spy series, which ran from 1965 to 1968 and was adapted for the big screen in 2002 as an Eddie Murphy and Owen Wilson vehicle. He also received a good amount of geek cred for his role as FBI agent Bill Maxwell in the cult superhero hit The Greatest American Hero, which ran from 1981 to 1986 and also is in line for a move to the big screen.
But Culp also had a film career. His most notable film work is the 1969 sex comedy, Bob & Carol & Ted & Alice. He also played a number of supporting roles later in his career, usually as an authority figure, most notably as Mayor Tyler in 1985’s Turk 182 and the President of the United States in 1993’s The Pelican Brief.
