As a child of around 10 YOA, I was a serious fan of Peter Gunn. I still remember the disappointment of turning the tv channel to Peter Gunn only to discover that it wasn't there anymore. I think, but am not sure, that this was my first encounter with Mr. Lucky. I was not pleased. My parents began watching Mr. Lucky on a regular basis. As there was only one television ( and but two stations), I also watched. Still angry about Peter Gunn it took several episodes for Mr. Lucky to grow on me but it did. Not as cool as Peter Gunn but suave and sophisticated (and of course, lucky), here was another character to admire. With Ross Martin, pre Wild Wild West, as a co-star, this was good television developed by the great Blake Edwards featuring smooth music by Henry Mancini. My child's tv world was once again secure. Then came the first blow, the casino mysteriously became a restaurant. Then the other shoe fell: cancellation. I never trusted television again which in retrospect, was a valuable lesson.
The main sponsor, Lever Brothers, insisted upon changing the casino to a restaurant in mid-season for reasons which are still somewhat murky to me. The show, still in its first and unfortunately last season, was a hit but the change was made anyway. The program remained popular but at the season end Lever dropped it. Another sponsor did not come forward. The reasons behind all of this are obscure but star, John Vivyan, blamed Jack Benny. You will have to look that up for yourself (try Television Obscurities and Wikipedia). Vivyan never starred in another tv program or movie. He did have a success with the play, Cactus Flower, in 1969 but did little acting afterwards.
This series and the Cary Grant movie are both based loosely on the same short story. However, they share but little except the title and the occupation of Mr. Lucky. I streamed this series via Amazon Prime so can not comment on any DVD's or Blu-rays.
