It stars Robert Wagner in his television debut as sophisticated thief Alexander Mundy, who works for the U.S. government in return for his release from prison.

In the main opening titles, his new SIA boss, Noah Bain, uses the catch phrase, "Oh, look, Al, I'm not asking you to spy.

In the series' third season, Throne was replaced by Edward Binns as Mundy's SIA boss, Wally Powers in some episodes.

As Throne explained: "They had this idea of shooting the whole season in Italy, but they wanted me to stay behind and give Wagner’s character...orders over the phone.

Also during the third season, Fred Astaire played Alistair Mundy, Alexander's father, in five episodes (four on screen, one voice over that's not credited).

It was creator Roland Kibbee's idea to have a semiregular on the show who was related to Wagner's character, Alexander Mundy.

Producer Glen Larson came up with the idea of how to introduce Alistair Mundy according to Wagner's autobiography, Pieces of My Heart.

Astaire's character makes his first appearance in the third season, episode four titled "The Great Casino Caper".

This formula where father and son team up to pull off a heist was often repeated when Alistair Mundy appeared.

In Region 4, Madman Entertainment has released the entire series on DVD in Australia and New Zealand as three season box sets.
