One of my favorite TV series as a kid was the British-produced adventure series The Persuaders! (1971-72) starring Roger Moore and Tony Curtis as two mismatched international playboys forced by a judge after their arrest to try to try to solve crimes the police cannot throughout Europe. I liked the pairing of the actors, the bevy of Sixties international starlets who guest-starred (Susan George, Suzanna Leigh, Suzy Kendall, etc.), the gorgeous scenery, and a wonderful musical score by John Barry. Unfortunately, the series could not find much of an audience during its first run opposite Mission: Impossible and was cancelled after one season.
