Besides Don Knotts, there are a number of actors from the Andy Griffith Show in this movie, some playing characters very similar to the characters they did in the Andy Griffith Show. For example, Hal Smith plays the town drunk in both productions, and Dorthy Neumann plays Smith's wife in both productions. Also, "Griffith" show veterans, such as Burt Mustin and Hope Summers are featured in this movie. This was Knott's first film after leaving the Andy Griffith Show.
