In this lesser-known companion series to Peter Gunn, Mr. Lucky is a suave but honest professional gambler who figures out how to operate a casino without breaking the law, by having it on a yacht moored in international waters outside the three-mile limit.
The series was created by famed writer/director Blake Edwards, loosely based on the 1943 film starring Cary Grant, which was based on an original story "Bundles for Freedom" by Milton Holmes.
Much of the show's atmosphere is provided by Henry Mancini's theme and incidental music, which produced two full albums, The Music From Mr. Lucky and Mr. Lucky Goes Latin. Of particular note, besides the theme, is "March of the Cue Balls" from episode 5. Mr. Lucky's pocket watch, when opened, plays the first five notes of the theme, corresponding to the words "They call him Luck-y".
Edwards helped revive the concept in 1980 as a TV-movie pilot called Casino, starring Mike Connors.
