This is truly a great TV series. it's funny , it's very smart , the acting is excellent. The Way Culp and Cosby play off or each other is marvelous, you felt that after the cameras stopped rolling they remained the closest of friends. The locations (most notably through Asia) are quite significant for the time as it was unheard of for an American tv show to be film in China and parts of the Far East. Almost every episode included a notable guest star. Quite a refreshing peace of television. I do remember "Nick at Night" re running the series void of syndication edits in the late 1980's Please don't judge the series by it's half hearted , feeble "Return of i spy" tv movie that aired on CBS I believe a few years back , this in no way represents the enormous quality of it's predecessor.
