Actor and singer Bobby Darin was cast in the second episode (October 5, 1959) with the unlikely name of "Honeyboy Jones". Less than a year earlier, Darin had rocketed to fame with his version of the song, "Mack the Knife".
Prior to being cast as Opie Taylor on The Andy Griffith Show, child actor Ron Howard played "Walker", a little boy temporarily left in Hennesey's care in the 1959 episode "The Baby Sitter". Gary Hunley, another child actor, appeared in the same episode.
Charles Bronson, en route to a long film career, was cast twice as Lt. Cmdr. Steve Ogrodowski, a Navy intelligence officer.
Other guest stars:
The series was notable for an extremely catchy theme tune (by Sonny Burke), a jazzy hornpipe played by tuba and piccolo. Hennesey was also innovative for being the first series to employ what has since become a standard device in television: beginning the dialog and action of each episode during opening credits.
Cooper starred in, produced and directed the series, drawing upon his real-life experience as a World War II Navy veteran and his continuing service for many years as an officer in the United States Naval Reserve. He was a former child actor who starred in the Our Gang comedies of the early 1930s and then moved into feature films.
In the series finale, "I, Thee Wed" (May 7, 1962), characters Chick and Martha marry.
Hennesey aired the pilot for the 1961-1962 CBS sitcom Mrs. G. Goes to College, also known as The Gertrude Berg Show, starring Gertrude Berg in the role of Cooper's "Aunt Sarah". In the last of Berg's television series, the character, as a 62-year-old widow, enrolls in college.
