Ground-breaking in many respects, I Spy was about two international playboys who were actually secret agents for the Pentagon. Robert Culp played tennis player Kelly Robinson, and Bill Cosby played his coach, Alexander “Scotty” Scott – becoming the first African-American ever to be cast in a lead role in a U.S. television show. Intended to be a TV version of James Bond, the personal chemistry between the two leads was undeniable, and many fans tuned in more for the hip banter than for the action. (Trivia: I Spy was one of the very few TV shows, before or since, that actually filmed in the exotic locations they said they were in.) It ran on NBC from 1965 to 1968; we have the entire series below.
